TSK · Deuteronomy 31:5

Be careful, lest you make a covenant with the inhabitants of the land where you are going, lest it be for a snare in the midst of you:

and when Yahweh your God shall deliver them up before you, and you shall strike them; then you shall utterly destroy them: you shall make no covenant with them, nor show mercy to them;

But Yahweh your God will deliver them up before you, and will confuse them with a great confusion, until they be destroyed.

As Yahweh commanded Moses his servant, so Moses commanded Joshua. Joshua did so. He left nothing undone of all that Yahweh commanded Moses.
