'Loose' in the Bible

The Lord then answered him, and said, Thou hypocrite, doth not each one of you on the sabbath loose his ox or his ass from the stall, and lead him away to watering?

Saying, Go ye into the village over against you; in the which at your entering ye shall find a colt tied, whereon yet never man sat: loose him, and bring him hither.

And if any man ask you, Why do ye loose him? thus shall ye say unto him, Because the Lord hath need of him.

And as they were loosing the colt, the owners thereof said unto them, Why loose ye the colt?
