The man waxed great - There is a strange and observable recurrence of the same term in the original: ויגדל האיש וילך הלוך וגדל עד כי גדל מאד vaiyigdal haish vaiyelech haloch vegadel ad ki gadal meod, And the man was Great; and he went, going on, and was Great, until that he was exceeding Great. How simple is this language, and yet how forcible!

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 Genesis 26:16.

Being thus blessed of Jehovah, Isaac became increasingly (הלוך, vid., Genesis 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).

And the man waxed great, and went forward, and grew until he became very great:

went...: Heb. went going

26:12-17 God blessed Isaac. Be it observed, for the encouragement of poor tenants who occupy other people's lands, and are honest and industrious, that God blessed him with a great increase. The Philistines envied Isaac. It is an instance of the vanity of the world; for the more men have of it, the more they are envied, and exposed to censure and injury. Also of the corruption of nature; for that is an ill principle indeed, which makes men grieve at the good of others. They made Isaac go out of their country. That wisdom which is from above, will teach us to give up our right, and to draw back from contentions. If we are wrongfully driven from one place, the Lord will make room for us in another.
