1. Mose 26:12

Isaac sowed in that land - Being now perfectly free from the fear of evil, he betakes himself to agricultural and pastoral pursuits, in which he has the especial blessing of God, so that his property becomes greatly increased. A hundred-fold - מאה שערים, meah shearim, literally, "A hundred-fold of barley;" and so the Septuagint, ἑκατοστευουσαν κριθην. Perhaps such a crop of this grain was a rare occurrence in Gerar. The words, however, may be taken in a general way, as signifying a very great increase; so they are used by our Lord in the parable of the sower.

Then Isaac sowed in that land--During his sojourn in that district he farmed a piece of land, which, by the blessing of God on his skill and industry, was very productive (Isa 65:13; Psa 37:19); and by his plentiful returns he increased so rapidly in wealth and influence that the Philistines, afraid or envious of his prosperity, obliged him to leave the place (Pro 27:4; Ecc 4:4). This may receive illustration from the fact that many Syrian shepherds at this day settle for a year or two in a place, rent some ground, in the produce of which they trade with the neighboring market, till the owners, through jealousy of their growing substance, refuse to renew their lease and compel them to remove elsewhere.

And the man waxed great,.... In substance, as well as in honour and glory, among men: and went forward; in the world, and in the increase of worldly things: and grew until he became very great: as he must needs be, since Abraham his father left him all that he had, who was very rich in cattle, in gold and silver, and had been increasing ever since; and especially since he came to Gerar, where he was gradually increasing, until he became to be exceeding great indeed, even the greatest man in all the country, yea, greater than King Abimelech himself, as it seems, from Gen 26:16.

Isaac's Increasing Wealth. - As Isaac had experienced the promised protection ("I will be with thee," Gen 26:3) in the safety of his wife, so did he received while in Gerar the promised blessing. He sowed and received in that year "a hundred measures," i.e., a hundred-fold return. This was an unusual blessing, as the yield even in very fertile regions is not generally greater than from twenty-five to fifty-fold (Niebuhr and Burckhardt), and it is only in the Ruhbe, that small and most fruitful plain of Syria, that wheat yields on an average eighty, and barley a hundred-fold. Agriculture is still practised by the Bedouins, as well as grazing (Robinson, Pal. i. 77, and Seetzen); so that Isaac's sowing was no proof that he had been stimulated by the promise of Jehovah to take up a settled abode in the promised land. Gen 26:13-17 Being thus blessed of Jehovah, Isaac became increasingly (הלוך, vid., Gen 8:3) greater (i.e., stronger), until he was very powerful and his wealth very great; so that the Philistines envied him, and endeavoured to do him injury by stopping up and filling with rubbish all the wells that had been dug in his father's time; and even Abimelech requested him to depart, because he was afraid of his power. Isaac then encamped in the valley of Gerar, i.e., in the "undulating land of Gerar," through which the torrent (Jurf) from Gerar flows from the south-east (Ritter, Erdk. 14, pp. 1084-5).

Here we have, I. The tokens of God's good-will to Isaac. He blessed him, and prospered him, and made all that he had to thrive under his hands. 1. His corn multiplied strangely, Gen 26:12. He had no land of his own, but took land of the Philistines, and sowed it; and (be it observed for the encouragement of poor tenants, that occupy other people's lands, and are honest and industrious) God blessed him with a great increase. He reaped a hundred fold; and there seems to be an emphasis laid upon the time: it was that same year when there was a famine in the land; while others scarcely reaped at all, he reaped thus plentifully. See Isa 65:13, My servants shall eat, but you shall be hungry, Psa 37:19, In the days of famine they shall be satisfied. 2. His cattle also increased, Gen 26:14. And then, 3. He had great store of servants, whom he employed and maintained. Note, As goods are increased those are increased that eat them, Ecc 5:11. II. The tokens of the Philistines' ill-will to him. They envied him, Gen 26:14. It is an instance, 1. Of the vanity of the world that the more men have of it the more they are envied, and exposed to censure and injury. Who can stand before envy? Pro 27:4. See Ecc 4:4. 2. Of the corruption of nature; for that is a bad principle indeed which makes men grieve at the good of others, as if it must needs be ill with me because it is well with my neighbor. (1.) They had already shown their ill-will to his family, by stopping up the wells which his father had digged, Gen 26:15. This was spitefully done. Because they had not flocks of their own to water at these wells, they would not leave them for the use of others; so absurd a thing is malice. And it was perfidiously done, contrary to the covenant of friendship they had made with Abraham, Gen 21:31,…

26:12-13 Isaac lived in the land as a temporary settler, enjoying abundant prosperity because of God’s blessing; his crops flourished and he became very rich.
