'Shut' in the Bible

And Ahimaaz calleth and saith unto the king, 'Peace;' and he boweth himself to the king, on his face, to the earth, and saith, 'Blessed is Jehovah thy God who hath shut up the men who lifted up their hand against my lord the king.'

And David cometh in unto his house at Jerusalem, and the king taketh the ten women-concubines -- whom he had left to keep the house, and putteth them in a house of ward, and sustaineth them, and unto them he hath not gone in, and they are shut up unto the day of their death, in widowhood living.
