Isaac is now the heir, and therefore the holder, of the promise. Hence, the Lord enters into communication with him. First, the present difficulty is met. "Go not down into Mizraim," the land of corn, even when other lands were barren. "Dwell in the land of which I shall tell thee." This reminds us of the message to Abraham Genesis 12:1. The land here spoken of refers to "all these lands" mentioned in the following verses. "Sojourn in this land:" turn aside for the present, and take up thy temporary abode here. Next, the promise to Abraham is renewed with some variety of expression. "I will be with thee" Genesis 21:22, a notable and comprehensive promise, afterward embodied in the name Immanuel, "God with us. Unto thee and unto thy seed." This was fulfilled to his seed in due time. All these lands, now parcelled out among several tribes. "And blessed in thy seed" Genesis 12:3; Genesis 22:18.

This is the great, universal promise to the whole human race through the seed of Abraham, twice explicitly announced to that patriarch. "All the nations." In constancy of purpose the Lord contemplates, even in the special covenant with Abraham, the gathering in of the nations under the covenant with Noah and with Adam Genesis 9:9; Hosea 6:7. "Because Abraham hearkened to my voice," in all the great moments of his life, especially in the last act of proceeding on the divine command to offer Isaac himself. Abraham, by the faith which flows from the new birth, was united with the Lord, his shield and exceeding great reward Genesis 15:1, with God Almighty, who quickened and strengthened him to walk before him and be perfect Genesis 17:1. The Lord his righteousness worketh in him, and his merit is reflected and reproduced in him Genesis 22:16, Genesis 22:18. Hence, the Lord reminds Isaac of the oath which he had heard at least fifty years before confirming the promise, and of the declaration then made that this oath of confirmation was sworn because Abraham had obeyed the voice of God. How deeply these words would penetrate into the soul of Isaac, the intended victim of that solemn day! But Abraham's obedience was displayed in all the acts of his new life. He kept the charge of God, the special commission he had given him; his commandments, his express or occasional orders; his statutes, his stated prescriptions, graven on stone; his laws, the great doctrines of moral obligation. This is that unreserved obedience which flows from a living faith, and withstands the temptations of the flesh.

Go not down into Egypt - As Abraham had taken refuge in that country, it is probable that Isaac was preparing to go thither also; and God, foreseeing that he would there meet with trials, etc., which might prove fatal to his peace or to his piety, warns him not to fulfill his intention.

And the Lord appeared unto him,.... In a vision or dream, when he was at Gerar:

and said, go not down into Egypt; as his father had done in the like case, and where Isaac thought to have gone, and the rather, as that was a fruitful country; and so the Targum of Jonathan,"and it was in the heart of Isaac to go down into Egypt, and the Lord appeared unto him, &c.''and charged him not to go thither; partly to try his faith in him, and dependence on his providence for support in this time of famine, and partly lest he should think of continuing there, and be unmindful of the promise of the land of Canaan to Abraham's seed:

dwell in the land which I shall tell thee of; even the land of Canaan, which he was now about to give him on account of the promise of it to Abraham and his seed, and to renew it to him and to his seed.

And the LORD appeared unto him, and said, {b} Go not down into Egypt; dwell in the land which I shall tell thee of:

(b) God's providence always watches to direct the ways of his children.

26:2 The Lord said, go not down into Egypt. Sojourn in this land - There was a famine in Jacob's days, and God bid him go down into Egypt, Gen 46:3,4, a famine in Isaac's days, and God bid him not go down: a famine in Abraham's days, and God left him to his liberty, directing him neither way, which (considering that Egypt was always a place of trial to God's people) some ground upon the different characters of these three patriarchs. Abraham was a man of very intimate communion with God, and to him all places and conditions were alike; Isaac a very good man, but not cut out for hardship, therefore he is forbidden to go to Egypt; Jacob inured to difficulties, strong and patient, and therefore he must go down into Egypt, that the trial of his faith might be to praise, and honour, and glory. Thus God proportions his people's trials to their strength.

Margin Go not down

Cf. See Scofield Note: "Gen 46:3".

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.
