'Purpose' in the Bible

To what purpose is the multitude of your sacrifices unto me? saith the LORD: I am full of the burnt offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he goats.

This is the purpose that is purposed upon the whole earth: and this is the hand that is stretched out upon all the nations.

For the Egyptians shall help in vain, and to no purpose: therefore have I cried concerning this, Their strength is to sit still.
