'Strengthen' in the Bible

For the seller shall not return to that which is sold, although they be yet alive: for the vision is touching the whole multitude of it, none shall return; neither shall any strengthen himself in the iniquity of his life.

Behold, this was the iniquity of your sister Sodom: pride, fullness of bread, and prosperous ease was in her and in her daughters; neither did she strengthen the hand of the poor and needy.

I will strengthen the arms of the king of Babylon, and put my sword in his hand: but I will break the arms of Pharaoh, and he shall groan before him with the groanings of a deadly wounded man.

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