'Purpose' in the Bible

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

And the land of Judah shall become a terror unto Egypt; every one to whom mention is made thereof shall be afraid, because of the purpose of Jehovah of hosts, which he purposeth against it.

For Egypt helpeth in vain, and to no purpose: therefore have I called her Rahab that sitteth still.
