Genesis 12:10

And there was a famine in the land — Not only to punish the iniquity of the Canaanites, but to exercise the faith of Abram. Now he was tried whether he could trust the God that brought him to Canaan, to maintain him there, and rejoice in him as the God of his salvation, when the fig — tree did not blossom. And Abram went down into Egypt — See how wisely God provides, that there should be plenty in one place, when there was scarcity in another; that, as members of the great body, we may not say to one another, I have no need of you.
