I wonder what Mathew 23:9 references?
“don’t call anyone Father...Don’t call anyone Rabbi and call no one instructor...”(all these found in the same general context of Matthew 23)
I think one can can make an interesting connection with the above to this passage from the Old Testament(note especially verse 34)...”Jeremiah 31:33-35”33“But this is the covenant I will make with the house of Israel after those days, declares the LORD. I will put My law in their minds and inscribe it on their hearts. And I will be their God, and they will be My people. 34No longer will each man teach his neighbor or his brother, saying, ‘Know the LORD,’ because they will all know Me, from the least of them to the greatest, declares the LORD. For I will forgive their iniquities and will remember their sins no more.” 35Thus says the LORD, who gives the sun for light by day, who sets in order the moon and stars for light by night, who stirs up the sea so that its waves roar—the LORD of Hosts is His name:…”
Hebrews 8:11 references it...”For this is the covenant I will make with the house of Israel after those days, declares the Lord. I will put My laws in their minds and inscribe them on their hearts. And I will be their God, and they will be My people. 11 No longer will each one teach his neighbor or his brother, saying, ‘Know the Lord,’ because they will all know Me, from the least of them to the greatest. 12For I will forgive their iniquities and will remember their sins no more.”…
I think what Christ was saying in Matthew 23 relates to what Jeremiah 31 and Hebrews 8 also says but the connection is so new to me I have to flesh it out fully.
