'Sustaineth' in the Bible

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.

I -- I have lain down, and I sleep, I have waked, for Jehovah sustaineth me.

Good is the man -- gracious and lending, He sustaineth his matters in judgment.

The spirit of a man sustaineth his sickness, And a smitten spirit who doth bear?
