John Chrysostom, on Heb 8:11

“And they shall not teach every man his neighbour and every man his brother, saying, Know the Lord: for all shall know me from the least to the greatest of them:”

“"And they shall not teach" (he says) "every man his neighbor, and every man his brother, saying, Know the Lord: for all shall know Me from the least to the greatest. For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more." Behold also another sign. "From the least even to the greatest of them" (he says) "they shall know Me, and they shall not say, Know the Lord." When hath this been fulfilled save now? For our religion is manifest: but theirs, i.e. the Jews', was not manifest, but had been shut up in a corner. A covenant is then said to be "new," when it is different and shows some advantage over the old. Here he shows that God counts us worthy of greater and of spiritual privileges: for it is said "their sound went out into all the earth and their words unto the ends of the world." (Ps. xix. 5; Rom. x. 18.) That is the meaning of "they shall not say each man to his neighbor, Know the Lord." And again, "the earth shall be filled with the knowledge of the Lord as much water to cover the seas." (Isa. xi. 9.)”
