Just as the Palestinian covenant has enlarged the promise of land originally given in the Abrahamic covenant, the Davidic covenant has enlarged the seed promise—that God would make Israel a “great nation” (Gen. 12:2) and multiply their descendants exceedingly (Gen. 17:2). This covenant is given to us in 2 Samuel 7:8-16 (and is also summarized in 1 Chron. 17:11-1 and 2 Chron. 6:16).
2 Samuel 7:8-16
“Now therefore, thus you shall say to My servant David, ‘Thus says the Lord of hosts,” I took you from the pasture, from following the sheep, that you should be ruler over My people Israel. 9 And I have been with you wherever you have gone and have cut off all your enemies from before you; and I will make you a great name, like the names of the great men who are on the earth. 10 I will also appoint a place for My people Israel and will plant them, that they may live in their own place and not be disturbed again, nor will the wicked afflict them any more as formerly, 11 even from the day that I commanded judges to be over My people Israel; and I will give you rest from all your enemies. The Lord also declares to you that the Lord will make a house for you. 12 When your days are complete and you lie down with your fathers, I will raise up your descendant after you, who will come forth from you, and I will establish his kingdom. 13 He shall build a house for My name, and I will establish the throne of his kingdom forever. 14 I will be a father to him and he will be a son to Me; when he commits iniquity, I will correct him with the rod of men and the strokes of the sons of men, 15 but My lovingkindness shall not depart from him, as I took it away from Saul, whom I removed from before you. 16 And your house and your kingdom shall endure before Me forever; your throne shall be established forever.”‘”
Here we see that Israel’s descendants will be multiplied and made great through the lineage of King David. Thus the original promise that Israel would become a “great nation” (Gen. 12:2) is seen in the greatness of David and his kingdom, then God’s kingdom; for the Messiah came through the lineage of David. And though we have thus far seen great carnage against the Jews, soon they will have rest from all their enemies forever.
