And it will nevermore be necessary for each one to teach his neighbor and his fellow citizen or each one his brother, saying, Know (perceive, have knowledge of, and get acquainted by experience with) the Lord, for all will know Me, from the smallest to the greatest of them.
People will no longer have to teach their ·neighbors [fellow citizens] and ·relatives [L brothers (and sisters)] ·to know the Lord [L saying, “Know the Lord”], because all people will know me, from the least to the ·most important [greatest].
Actually, however, God does show himself dissatisfied for he says to those under the first agreement: ‘Behold, the days are coming, says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah—not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they did not continue in my covenant, and I disregarded them, says the Lord. For this is the covenant that I will make with the house of Israel: After those days, says the Lord, I will put my laws in their mind and write them on their hearts; and I will be their God, and they shall be my people. None of them shall teach his neighbour, and none his brother, saying, Know the Lord, for all shall know me, from the least to the greatest of them. For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more’.
But Jesus’ priestly work far surpasses what these other priests do, since he’s working from a far better plan. If the first plan—the old covenant—had worked out, a second wouldn’t have been needed. But we know the first was found wanting, because God said, Heads up! The days are coming when I’ll set up a new plan for dealing with Israel and Judah. I’ll throw out the old plan I set up with their ancestors when I led them by the hand out of Egypt. They didn’t keep their part of the bargain, so I looked away and let it go. This new plan I’m making with Israel isn’t going to be written on paper, isn’t going to be chiseled in stone; This time I’m writing out the plan in them, carving it on the lining of their hearts. I’ll be their God, they’ll be my people. They won’t go to school to learn about me, or buy a book called God in Five Easy Lessons. They’ll all get to know me firsthand, the little and the big, the small and the great. They’ll get to know me by being kindly forgiven, with the slate of their sins forever wiped clean. By coming up with a new plan, a new covenant between God and his people, God put the old plan on the shelf. And there it stays, gathering dust.
People will not teach their neighbor anymore. They will not say to one another, ‘Know the Lord.’ That’s because everyone will know me. From the least important to the most important, all of them will know me.
"V’LO YELAMMEDU OD ISH ES RE’EHU V’ISH ES AKHIV LEMOR, DE’U ES HASHEM; KI KHULAM YEDE’U OTI LEMIKTANNAM V’AD GEDOLAM" ("No longer will a man teach his neighbor, or a man his brother, saying ‘Have da’as of Hashem,’ because they will all have da’as of Me, from the least of them to the greatest.")
