Now there was a famine in the land. So Abram went down to Egypt to sojourn there, for the famine was severe in the land.
Genesis 12:10

This verse contains an obvious little #chiasm.

Famine > Sojourn in Egypt < Famine.

Famine and exile are metaphors of separation from God. Spiritual famine ends when we learn to be in the world without being of the world.
