and now, do it, for Jehovah hath spoken of David saying, By the hand of David my servant, to save My people Israel out of the hand of the Philistines, and out of the hand of all their enemies.'

For the Lord has said of David, By the hand of my servant David I will make my people Israel safe from the Philistines, and from all who are against them.

The Lord hath spoken of David - Where is this spoken? Such a promise is not extant. Perhaps it means no more than, "Thus, it may be presumed, God hath determined."

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.
