'Maintain' in the Bible

The Lord God took the man and placed him in the orchard in Eden to care for it and to maintain it.

And there will I maintain thee; for yet there are five years of famine; in order that thou be not impoverished, thou, and thy household, and all that thou hast.

And now, fear not: I will maintain you and your little ones. And he comforted them, and spoke consolingly to them.
