'Loose' in the Bible

Then Joshua, the son of Nun, sent two men from Shittim secretly, with the purpose of searching out the land, and Jericho. So they went and came to the house of a loose woman of the town, named Rahab, where they took their rest for the night.

And the captain of the LORD'S host said unto Joshua, Loose thy shoe from off thy foot; for the place whereon thou standest is holy. And Joshua did so.

And the town will be put to the curse, and everything in it will be given to the Lord: only Rahab, the loose woman, and all who are in the house with her, will be kept safe, because she kept secret the men we sent.

Then Joshua said to the two men who had been sent to make a search through the land, Go into the house of the loose woman, and get her out, and all who are with her, as you gave her your oath.

But Joshua kept Rahab, the loose woman, and her father's family and all she had, from death, and so she got a living-place among the children of Israel to this day; because she kept safe the men whom Joshua had sent to make a search through the land.

That now you are turned back from the Lord? and, because you are false to him today, tomorrow his wrath will be let loose on all the people of Israel.
