By every word of the Lord doth man live By every, or any thing which God appoints and blesses for this end, how unlikely soever it may seem to be for the support and nourishment of the human frame. For it is not the creature, without God, that is sufficient for the support of life; it is only his command and blessing that makes it sufficient. We ought not, therefore, to fix our dependance, as we are prone to do, on natural causes, but to remember that we depend, absolutely, entirely, and immediately, on him for life and all things.

3 And he humbled thee, and suffered thee to hunger, and fed thee with manna, which thou knewest not, neither did thy fathers know; that he might make thee know that man doth not live by bread only, but by every word that proceedeth out of the mouth of the LORD doth man live.
