'Loose' in the Bible

The Lord therefore answered him and said, Hypocrites! does not each one of you on the sabbath loose his ox or his ass from the manger and leading it away, water it?

saying, Go into the village over against you, in which ye will find, on entering it, a colt tied up, on which no child of man ever sat at any time: loose it and lead it here.

And if any one ask you, Why do ye loose it? thus shall ye say to him, Because the Lord has need of it.

And as they were loosing the colt, its masters said to them, Why loose ye the colt?
