Here is the scripture that supports the idea that the animals were vegetarian prior to the fall and will be again after the final judgement.
Isaiah 65:25
The wolf and the lamb shall graze together, and the lion shall eat straw like the ox; and dust shall be the serpent's food. They shall do no evil or harm in all My holy mountain," says the LORD. (NASB)
“Isaiah 65:25
The wolf and the lamb shall graze together, and the lion shall eat straw like the ox; and dust shall be the serpent’s food. They shall do no evil or harm in all My holy mountain,” says the LORD. (NASB)”
In context ...
Isaiah 65 ...
17 For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
Isaiah 65:25
The wolf and the lamb shall graze together, and the lion shall eat straw like the ox; and dust shall be the serpent’s food. They shall do no evil or harm in all My holy mountain,” says the LORD. (NASB)
No. Isaiah is prophesying about the post-tribulation earth. There is another scripture which indicates the lion will lie down with the lamb, and a young boy will shepherd. THIS REFUTES THE LONGSTANDING MYTH THAT MOST OF THE RIGHTEOUS WILL GO TO HEAVEN. Next read Isaiah 65:21 - “My people will live in the houses they build; they will enjoy grapes from their own vineyards”. Guess what folks, the destiny of most of us righteous will be a similar setting to what Adam & Eve were in - a perfect place and a perfect body to go with it.
I forgot to respond and say thanks for posting that Scripture.
There’s also this one:
Genesis 1:30
And to every beast of the earth, and to every fowl of the air, and to everything that creeps upon the earth, wherein there is life, I have given every green plant for food: and it was so.
