How hard of a message was that? We need not only to hear but obey His voice to receive the blessing.
“Now there was a famine in the land—besides the previous famine in Abraham’s time—and Isaac went to Abimelek king of the Philistines in Gerar. The Lord appeared to Isaac and said, “Do not go down to Egypt; live in the land where I tell you to live. Stay in this land for a while, and I will be with you and will bless you. For to you and your descendants I will give all these lands and will confirm the oath I swore to your father Abraham.”
Genesis 26:1-3 NIV
