Genesis 20:1-2

_ _ 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, Genesis 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 (Genesis 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, Jeremiah 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 Judges 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.
