'Strengthen' in the Bible

And I will strengthen the arm of the king of Babylon, and I will give my sword into his hand, and I will break the arms of Pharaoh, and he will groan [with the] groaning of [the] mortally wounded {before him}.

And I will strengthen the arm of the king of Babylon, and the arms of Pharaoh will fall. And they will know that I [am] Yahweh when I give my sword into the hand of the king of Babylon, and he will stretch it out to the land of Egypt.

"I will seek the lost, and I will bring back the scattered, and I will bind [up] the one hurt, and I will strengthen the sick; and the fat and the strong I will destroy. I will feed her with justice."
