'Exhausted' in the Bible

Eventually, the king and his entourage arrived exhausted at their destination, and David refreshed himself there.

but Eleazar remained standing right where he was and fought so hard against the Philistines that he became exhausted he couldn't even let go of his sword! The LORD magnificently delivered them that day. After Eleazar had won the battle, the other soldiers returned, but only to strip the weapons and armor from the dead.
