And the three mighty men brake through the host of the Philistines, and drew water out of the well of Bethlehem, that was by the gate, and took it, and brought it to David: nevertheless he would not drink thereof, but poured it out unto the Lord. And he said, Be it far from me, O Lord, that I should do this: is not this the blood of the men that went in jeopardy of their lives? therefore he would not drink it. (2 Samuel 23:16-17)

Here, David clearly calls drinking water human blood, and consistent with the command of Deuteronomy 12:16; 15:23 (cf. Lv. 17:10,11), he poured it on to the ground, and did so as an act of worship unto the Lord. What David did not do was contrive some metaphysical justification for drinking this, but to be consistent with the professed plain-language hermeneutic Catholics insist they hold to in regards to "this is my body," then they should also insist this was literal in this case. As well as when God clearly states that the Canaanites were “bread:

• “Only rebel not ye against the LORD, neither fear ye the people of the land; for they are bread for us” (Num. 14:9)

Other examples of the use of figurative language for eating and drinking include,

• The Promised Land was “a land that eateth up the inhabitants thereof.” (Num. 13:32)

• David said that his enemies came to “eat up my flesh.” (Ps. 27:2)

• And complained that workers of iniquity ”eat up my people as they eat bread , and call not upon the Lord.” (Psalms 14:4)

• And the Lord also said, “I will consume man and beast; I will consume the fowls of the heaven, and the fishes of the sea, and the stumblingblocks with the wicked; and I will cut off man from off the land, saith the Lord.” (Zephaniah 1:3)

• While even arrows can drink: “I will make mine arrows drunk with blood, and my sword shall devour flesh ; and that with the blood of the slain and of the captives, from the beginning of revenges upon the enemy.' (Deuteronomy 32:42)

• But David says the word of God (the Law) was “sweeter also than honey and the honeycomb. (Psalms 19:10)

• Another psalmist also declared the word as “sweet:” “How sweet are thy words unto my taste! yea, sweeter than honey to my mouth!” (Psalms 119:103)

• Jeremiah likewise proclaimed, “Your words were found. and I ate them. and your word was to me the joy and rejoicing of my heart” (Jer. 15:16)

• Ezekiel was told to eat the words, “open thy mouth, and eat that I give thee...” “eat that thou findest; eat this scroll, and go, speak to the house of Israel.” (Ezek. 2:8; 3:1)

• John is also commanded, “Take the scroll ... Take it and eat it.” (Rev. 10:8-9 )

And Scripture refers to Christ being spiritual food and drink which even OT believers consumed:

• And did all eat the same spiritual meat; "And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ." (1 Corinthians 10:3-4)

• And Christ's word in Jn. 6, "I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst," (John 6:35) are correspondent to,

"Wherefore do ye spend money for that which is not bread? and your labour for that which satisfieth not? hearken diligently unto me, and eat ye that which is good, and let your soul delight itself in fatness. Incline your ear, and come unto me: hear, and your soul shall live; and I will make an everlasting covenant with you, even the sure mercies of David." (Isaiah 55:2-3)

• Moreover, like as bread is broken, Is. 53:10 states that "it pleased the Lord to bruise him," and the word for "bruise" (da^ka^') means to crumble, to break..., (Strong's). And like as wine is poured out, so Is. 53:12 also states of Christ, "he hath poured out his soul unto death," both of which are correspondent to the words of the Last Supper regarding bread and wine.

And which use of figurative language for Christ and spiritual things abounds in John, using the physical to refer to the spiritual:

Much more , by the grace of God.

Here's where it started...

Matthew 26:17-19

(ESV)

¹⁷Now on the first day of Unleavened Bread the disciples came to Jesus, saying, “Where will you have us prepare for you to eat the Passover?” ¹⁸He said, “Go into the city to a certain man and say to him, ‘The Teacher says, My time is at hand. I will keep the Passover at your house with my disciples.’” ¹⁹And the disciples did as Jesus had directed them, and they prepared the Passover .

Mark 14:12-16 (HCSB)

12 On the first day of Unleavened Bread, when they sacrifice the Passover lamb, His disciples asked Him, “Where do You want us to go and prepare the Passover so You may eat it?”
13 So He sent two of His disciples and told them, “Go into the city, and a man carrying a water jug will meet you. Follow him. 14 Wherever he enters, tell the owner of the house, ‘The Teacher says, “Where is the guest room for Me to eat the Passover with My disciples?”’ 15 He will show you a large room upstairs, furnished and ready. Make the preparations for us there.” 16 So the disciples went out, entered the city, and found it just as He had told them, and they prepared the Passover .

Luke 22:7-13 (HCSB)

7 Then the Day of Unleavened Bread came when the Passover lamb had to be sacrificed. 8 Jesus sent Peter and John, saying, “Go and prepare the Passover meal for us, so we can eat it.”
9 “Where do You want us to prepare it?” they asked Him.
10 “Listen,” He said to them, “when you’ve entered the city, a man carrying a water jug will meet you. Follow him into the house he enters. 11 Tell the owner of the house, ‘The Teacher asks you, “Where is the guest room where I can eat the Passover with My disciples?”’ 12 Then he will show you a large, furnished room upstairs. Make the preparations there.”
13 So they went and found it just as He had told them, and they prepared the Passover.

...and here is how it went down...

Matthew 26:26–28
26 Now as they were eating, Jesus took bread, and after blessing it broke it and gave it to the disciples, and said, “Take, eat; this is my body.” 27 And he took a cup, and when he had given thanks he gave it to them, saying, “Drink of it, all of you, 28 for this is my blood of the covenant, which is poured out for many for the forgiveness of sins.

Mark 14:22–24
22 And as they were eating, he took bread, and after blessing it broke it and gave it to them, and said, “Take; this is my body.” 23 And he took a cup, and when he had given thanks he gave it to them, and they all drank of it. 24 And he said to them, “This is my blood of the covenant, which is poured out for many.

Luke 22:19–20
19 And he took bread, and when he had given thanks, he broke it and gave it to them, saying, “This is my body, which is given for you. Do this in remembrance of me.” 20 And likewise the cup after they had eaten, saying, “This cup that is poured out for you is the new covenant in my blood.

(And just what is this? The yearly Passover where the Jews REMEMBER the salvation of the Lord.)

...and here is what Paul added later...

1 Corinthians 11:17-34

17 In the following directives I have no praise for you, for your meetings do more harm than good. 18 In the first place, I hear that when you come together as a church, there are divisions among you, and to some extent I believe it. 19 No doubt there have to be differences among you to show which of you have God’s approval. 20 So then, when you come together, it is not the Lord’s Supper you eat, 21 for when you are eating, some of you go ahead with your own private suppers. As a result, one person remains hungry and another gets drunk. 22 Don’t you have homes to eat and drink in? Or do you despise the church of God by humiliating those who have nothing? What shall I say to you? Shall I praise you? Certainly not in this matter!

23 For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, 24 and when he had given thanks, he broke it and said, “This is my body, which is for you; do this in remembrance of me.” 25 In the same way, after supper he took the cup, saying, “This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me.” 26 For whenever you eat this bread and drink this cup, you proclaim the Lord’s death until he comes.
27 So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord.

28 Everyone ought to examine themselves before they eat of the bread and drink from the cup. 29 For those who eat and drink without discerning the body of Christ eat and drink judgment on themselves. 30 That is why many among you are weak and sick, and a number of you have fallen asleep. 31 But if we were more discerning with regard to ourselves, we would not come under such judgment. 32 Nevertheless, when we are judged in this way by the Lord, we are being disciplined so that we will not be finally condemned with the world.
33 So then, my brothers and sisters, when you gather to eat, you should all eat together. 34 Anyone who is hungry should eat something at home, so that when you meet together it may not result in judgment.
And when I come I will give further directions.

So; just what happened between the Gospels yearly Passover that Jesus partook in, and Paul's description of meals that were entirely different??
