Genesis 26:17

“And Isaac departed thence, etc.] At once, peaceably and quietly, though to his loss and disadvantage, without taking himself either to argument or arms, in favour of himself; he departed immediately, as soon as he perceived his abode was disagreeable to the king and his people; which gives us a very agree, able idea of the calm and peaceable disposition of Isaac: and pitched his tent in the valley of Gerar, and dwelt there; at some distance from the city of Gerar, as Jarchi observes. Josephus f1422 says it was not far from it; but how far is not certain; very probably it was not out of the country, though on the borders of it. Some render it, “the brook of Gerar” f1423, and interpret it,…”

“valley of Gerar--torrent-bed or wady, a vast undulating plain, unoccupied and affording good pasture.”

“26:17-22 Isaac moved . . . to the Gerar Valley (away from the city of Gerar itself, 26:6, but probably still within ten miles) and reopened his father’s wells. Isaac was also opposed there, but chose not to fight back; he relinquished one well after another until God’s blessing outdid the opposition. Whenever Isaac reopened a well, and regardless of how often enemies caused them to cave in, he found water. God was blessing Isaac and that blessing could not be hindered. Finally, the Philistines left Isaac alone.”
