261 Then came a time of great need in the land, like that which had been before in the days of Abraham. And Isaac went to Abimelech, king of the Philistines, at Gerar. 2 And the Lord came to him in a vision and said, Do not go down to Egypt; keep in the land of which I will give you knowledge: 3 Keep in this land, and I will be with you and give you my blessing; for to you and to your seed will I give all these lands, giving effect to the oath which I made to your father Abraham; 4 I will make your seed like the stars of heaven in number, and will give them all these lands, and your seed will be a blessing to all the nations of the earth; 5 Because Abraham gave ear to my voice and kept my words, my rules, my orders, and my laws.
6 So Isaac went on living in Gerar;

Commentary on Genesis 26:1-5
(Read Genesis 26:1-5)
Isaac had been trained up in a believing dependence upon the Divine grant of the land of Canaan to him and his heirs; and now that there is a famine in the land, Isaac still cleaves to the covenant. The real worth of God's promises cannot be lessened to a believer by any cross providences that may befall him. If God engage to be with us, and we are where he would have us to be, nothing but our own unbelief and distrust can prevent our comfort. The obedience of Abraham to the Divine command, was evidence of that faith, whereby, as a sinner, he was justified before God, and the effect of that love whereby true faith works. God testifies that he approved this obedience, to encourage others, especially Isaac.
Commentary on Genesis 26:6-11
(Read Genesis 26:6-11)
There is nothing in Isaac's denial of his wife to be imitated, nor even excused. The temptation of Isaac is the same as that which overcame his father, and that in two instances. This rendered his conduct the greater sin. The falls of those who are gone before us are so many rocks on which others have split; and the recording of them is like placing buoys to save future mariners. This Abimelech was not the same that lived in Abraham's days, but both acted rightly. The sins of professors shame them before those that are not themselves religious.
