'Strength' in the Bible

All her majesty has gone away from the daughter of Zion; her princes have become like young stags that have not found pasture; they have gone away without strength, before the pursuer.

My rebellion was bound [as] a yoke, with his hand it was fastened together; it was put on my neck [and] caused my strength to fail. The Lord gave me into the hands [of those whom] I cannot withstand.
