'Sustained' in the Bible

But Isaac replied to Esau, “Behold, I have made him your master, and all his relatives I have given to him as servants; and with grain and new wine I have sustained him. Now as for you then, what can I do, my son?”

Now Barzillai was very old, being eighty years old; and he had sustained the king while he stayed at Mahanaim, for he was a very great man.

By You I have been sustained from my birth;You are He who took me from my mother’s womb;My praise is continually of You.
