'Sustain' in the Bible

Solomon had twelve governors over all Israel, and they sustained the king and his palace, {each one was to sustain for each month of the year}.

It shall be that you shall drink from the wadi, and I have commanded the crows to sustain you there."

"Get up and go to Zarephath which belongs to Sidon and stay there. Look, I have commanded a woman there, a widow, to sustain you."
