تكوين ٢٦:١

Renewal of the Promise. - A famine "in the land" (i.e., Canaan, to which he had therefore returned from Hagar's well; Gen 25:11), compelled Isaac to leave Canaan, as it had done Abraham before. Abraham went to Egypt, where his wife was exposed to danger, from which she could only be rescued by the direct interposition of God. Isaac also intended to go there, but on the way, viz., in Gerar, he received instruction through a divine manifestation that he was to remain there. As he was the seed to whom the land of Canaan was promised, he was directed not to leave it. To this end Jehovah assured him of the fulfilment of all the promises made to Abraham on oath, with express reference to His oath (Gen 22:16) to him and to his posterity, and on account of Abraham's obedience of faith. The only peculiarity in the words is the plural, "all these lands." This plural refers to all the lands or territories of the different Canaanitish tribes, mentioned in Gen 15:19-21, like the different divisions of the kingdom of Israel or Judah in Ch1 13:2; Ch2 11:23. האל; an antique form of האלּה occurring only in the Pentateuch. The piety of Abraham is described in words that indicate a perfect obedience to all the commands of God, and therefore frequently recur among the legal expressions of a later date. יהוה משׁמרת שׁמר "to take care of Jehovah's care," i.e., to observe Jehovah, His persons, and His will, Mishmereth, reverence, observance, care, is more closely defined by "commandments, statutes, laws," to denote constant obedience to all the revelations and instructions of God.

Here, I. God tried Isaac by his providence. Isaac had been trained up in a believing dependence upon the divine grant of the land of Canaan to him and his heirs; yet now there is a famine in the land, Gen 26:1. What shall he think of the promise when the promised land will not find him bread? Is such a grant worth accepting, upon such terms, and after so long a time? Yes, Isaac will still cleave to the covenant; and the less valuable Canaan in itself seems to be the better he is taught to value it, 1. As a token of God's everlasting kindness to him; and, 2. As a type of heaven's everlasting blessedness. Note, The intrinsic worth of God's promises cannot be lessened in a believer's eye by any cross providences. II. He directed him under this trial by his word. Isaac finds himself straitened by the scarcity of provisions. Somewhere he must go for supply; it should seem, he set out for Egypt, whither his father went in the like strait, but he takes Gerar in his way, full of thoughts, no doubt, which way he had best steer his course, till God graciously appeared to him, and determined him, abundantly to his satisfaction. 1. God bade him stay where he was, and not go down into Egypt: Sojourn in this land, Gen 26:2, Gen 26:3. There was a famine in Jacob's days, and God bade him go down into Egypt (Gen 46:3, Gen 46:4), a famine in Isaac's days, and God bade him not to go down, a famine in Abraham's days, and God left him to his liberty, directing him neither way. This variety in the divine procedure (considering that Egypt was always a place of trial and exercise to God's people) some ground upon the different characters of these three patriarchs. Abraham was a man of very high attainments, and intimate communion with God; and to him all places and conditions were alike. Isaac…

26:1-35 In this digression from Jacob’s story, Isaac’s prosperity (ch 26) shows that the blessing had passed to him (cp. 25:11) despite his failures of faith. 26:1 This Abimelech is probably not the man in ch 20, for these events could have been 90 years apart. Possibly Abimelech was a dynastic name or title (a later King Achish, 1 Sam 21:10, was also called Abimelech, Ps 34:title).
