'Strengthen' in the Bible

Behold, this was the iniquity of thy sister Sodom: pride, fulness of bread, and careless ease was in her and in her daughters, but she did not strengthen the hand of the poor and needy.

And I will strengthen the arms of the king of Babylon, and put my sword in his hand; and I will break Pharaoh's arms, so that he shall groan before him with the groanings of a deadly-wounded man.

And I will strengthen the arms of the king of Babylon, and the arms of Pharaoh shall fall down; and they shall know that I am Jehovah, when I have put my sword into the hand of the king of Babylon, and he shall have stretched it out upon the land of Egypt.

I will seek the lost, and bring again that which was driven away, and will bind up the broken, and will strengthen that which was sick; but I will destroy the fat and the strong: I will feed them with judgment.
