Here is, 1. Abraham's removal from Mamre, where he had lived nearly twenty years, into the country of the Philistines: He sojourned in Gerar, Gen 20:1. We are not told upon what occasion he removed, whether terrified by the destruction of Sodom, or because the country round was for the present prejudiced by it, or, as some of the Jewish writers say, because he was grieved at Lot's incest with his daughters, and the reproach which the Canaanites cast upon him and his religion, for his kinsman's sake: doubtless there was some good cause for his removal. Note, In a world where we are strangers and pilgrims we cannot expect to be always in the same place. Again, Wherever we are, we must look upon ourselves but as sojourners. 2. His sin in denying his wife, as before (Gen 12:13), which was not only in itself such an equivocation as bordered upon a lie, and which, if admitted as lawful, would be the ruin of human converse and an inlet to all falsehood, but was also an exposing of the chastity and honour of his wife, of which he ought to have been the protector. But, besides this, it had here a two-fold aggravation: - (1.) He had been guilty of this same sin before, and had been reproved for it, and convinced of the folly of the suggestion which induced him to it; yet he returns to it. Note, It is possible that a good man may, not only fall into sin, but relapse into the same sin, through the surprise and strength of temptation and the infirmity of the flesh. Let backsliders repent then, but not despair, Jer 3:22. (2.) Sarah, as it should seem, was now with child of the promised seed, or, at least, in expectation of being so quickly, according to the word of God; he ought therefore to have taken particular care of her now, as Jdg 13:4. 3. The peril that Sarah was brought into by this means: The king of Gerar sent, and took her to his house, in order to the taking of her to his bed. Note, The sin of one often occasions the sin of others; he that breaks the hedge of God's commandments opens a gap to he knows not how many; the beginning of sin is as the letting forth of water.

And Abraham journeyed - It is very likely that this holy man was so deeply affected with the melancholy prospect of the ruined cities, and not knowing what was become of his nephew Lot and his family, that he could no longer bear to dwell within sight of the place. Having, therefore, struck his tents, and sojourned for a short time at Kadesh and Shur, he fixed his habitation in Gerar, which was a city of Arabia Petraea, under a king of the Philistines called Abimelech, my father king, who appears to have been not only the father of his people, but also a righteous man.

And Abraham journeyed from thence towards the south country,.... He returned from the plains or oaks of Mamre, where he had lived fifteen or twenty years, into the more southern parts of the land of Canaan: the reason of this remove is not certain; some think, because he could not bear the stench of the sulphurous lake, the cities of Sodom and Gomorrah were become; and others, because of the scandal of Lot's incest with his daughters, which prejudiced the idolatrous people in those parts more against the true religion; neither of which are likely, by reason of the distance; but the better reason seems to be, that it was so ordered in Providence that he should remove from place to place, that it might appear that he was but a sojourner in the land:

and dwelt between Kadesh and Shur; two wildernesses, as Jerom says (y), one of which joined to Egypt, to which the people of Israel went when they passed over the Red sea, and the other, Kadesh, reached to the desert of the Saracens. Onkelos and Jonathan paraphrase the words between Rekam and Chagra, or Hagra, the same place where the angel of the Lord met with Hagar at the well; see Gill on Gen 16:7 and See Gill on Gen 16:14,

and sojourned in Gerar; or Gerara, as Jerom (z) calls it,"from whence he says the Geraritic country in his time beyond Daroma, or the south, had its name, and was twenty five miles distance from Eleutheropolis to the south, and was formerly the southern border of the Canaanites, and the metropolis of Palestine.''According to the Samaritan version, Gerar is the same with Ashkelon, which was afterwards, when aristocracy took place in this country, one of the five lordships of the Philistines; and so says Africanus (a); and that Gerar was in the country of the Philistines, and Abimelech was king of them, is clear from Gen 21:32. This place was about six miles from Mamre (b), from whence Abraham removed.
