'Close' in the Bible

When you get close to the Ammonites, don’t show any hostility to them or fight with them, for I will not give you any of the Ammonites’ land as a possession; I have given it as a possession to the descendants of Lot.’”

Then the Lord’s anger will burn against you. He will close the sky, and there will be no rain; the land will not yield its produce, and you will perish quickly from the good land the Lord is giving you.
