Genesis 12:10 (KJV) And there was a famine in the land: and Abram went down into Egypt to sojourn there; for the famine was grievous in the land.
Egypt is a type of the world. Where do you go when famine comes your way? Do you wait on God or do you turn to the world?
Genesis 26:1-3 (KJV) 1 And there was a famine in the land, beside the first famine that was in the days of Abraham. And Isaac went unto Abimelech king of the Philistines unto Gerar. 2 And the LORD appeared unto him, and said, Go not down into Egypt; dwell in the land which I shall tell thee of: 3 Sojourn in this land, and I will be with thee, and will bless thee; for unto thee, and unto thy seed, I will give all these countries, and I will perform the oath which I sware unto Abraham thy father;
God says do not turn to Egypt – to the world – when famine comes. Trust God and he will bless you.
