'Maintained' in the Bible

And Barzillai was very aged, eighty years old; and it was he that had maintained the king while he abode at Mahanaim; for he was a very great man.

And David came to his house at Jerusalem; and the king took the ten women, concubines, whom he had left to keep the house, and put them in a house of confinement and maintained them, but did not go in to them. So they were shut up unto the day of their death, living in widowhood.
