Deuteronomy 7:22

The Lord thy God will put out. — The word for “putting out” is illustrated by its use in Deuteronomy 19:5, of the axe-head flying off from the handle in the midst of a blow, and of the olive “casting” his fruit in Deuteronomy 28:40. (Comp. also 2 Kings 16:6, and 1 Samuel 25:29, for a similar thought.)

By little and little. — This confirms the view already expressed, that the expulsion of each particular nation was contingent upon the Divine decree, and that none were to be attacked by Israel except when the Lord should deliver them into Israel’s hand.
