'Steady' in the Bible

Yet his bow remained steady,and his strong arms were made agileby the hands of the Mighty One of Jacob,by the name of the Shepherd, the Rock of Israel,

When Moses’ hands grew heavy, they took a stone and put it under him, and he sat down on it. Then Aaron and Hur supported his hands, one on one side and one on the other so that his hands remained steady until the sun went down.

Make my steps steady through Your promise;don’t let any sin dominate me.

Strengthen the weak hands,steady the shaking knees!
