'Loose' in the Bible

But the Lord gave him an answer and said, O you false men! do you not, every one of you, on the Sabbath, let loose his ox and his ass and take it to the water?

What man of you, having a hundred sheep, if one of them gets loose and goes away, will not let the ninety-nine be in the waste land by themselves, and go after the wandering one, till he sees where it is?

Saying, Go into the little town in front of you, and on going in you will see a young ass fixed with a cord, on which no man has ever been seated; let him loose and take him.
