2 Samuel 3:18

Now then do [it]
Make him your king, and I shall no longer oppose it as I have done:

for the Lord hath spoken of David;
concerning his being king, and the saviour of his people Israel:

saying, by the hand of my servant David I will save my people Israel
out of the hand of the Philistines, and out of the hand of all their
enemies;
and which, though where recorded in so many words, yet was the sense of the promise of making him king, and the design of his unction; and besides they might have been spoken to Samuel, though not written; and which he might report, and so might pass from one to another to be generally known.
