Isaac had now laid aside all thoughts of going to Egypt, and, in obedience to the heavenly vision, sets up his staff in Gerar, the country in which he was born (Gen 26:6), yet there he enters into temptation, the same temptation that his good father had been once and again surprised and overcome by, namely, to deny his wife, and to give out that she was his sister. Observe,

I.How he sinned, Gen 26:7. Because his wife was handsome, he fancied the Philistines would find some way or other to take him off, that some of them might marry her; and therefore she must pass for his sister. It is an unaccountable thing that both these great and good men should be guilty of so strange a piece of dissimulation, by which they so much exposed both their own and their wives' reputation. But we see, 1. That very good men have sometimes been guilty of very great faults and follies. Let those therefore that stand take heed lest they fall, and those that have fallen not despair of being helped up again. 2. That there is an aptness in us to imitate even the weaknesses and infirmities of those we have a value for. We have need therefore to keep our foot, lest, while we aim to tread in the steps of good men, we sometimes tread in their by-steps.

II.How he was detected, and the cheat discovered, by the king himself. Abimelech (not the same that was in Abraham's days, ch. 20, for this was nearly 100 years after that, but this was the common name of the Philistine kings, as Caesar of the Roman emperors) saw Isaac more familiar and pleasant with Rebekah than he knew he would be with his sister (Gen 26:8): he saw him sporting with her, or laughing; it is the same word with that from which Isaac has his name. He was rejoicing with the wife of his youth, Pro 5:18. It becomes those in that relation to be pleasant with one another, as those that are pleased with one another. Nowhere may a man more allow himself to be innocently merry than with his own wife and children. Abimelech charged him with the fraud (Gen 26:9), showed him how frivolous his excuse was and what might have been the bad consequences of it (Gen 26:10), and then, to convince him how groundless and unjust his jealousy of them was, took him and his family under his particular protection, forbidding any injury to be done to him or his wife upon pain of death, Gen 26:11. Note, 1. A lying tongue is but for a moment. Truth is the daughter of time; and, in time, it will out. 2. One sin is often the inlet to many, and therefore the beginnings of sin ought to be avoided. 3. The sins of professors shame them before those that are without. 4. God can make those that are incensed against his people, though there may be some colour of cause for it, to know that it is at their peril if they do them any hurt. See Psa 105:14, Psa 105:15.

Abraham obeyed my voice - מימרי meimeri, my Word. See Gen 15:1.

My charge - משמרתי mishmarti, from שמר shamar, he kept, observed, etc., the ordinances or appointments of God. These were always of two kinds:

1.Such as tended to promote moral improvement, the increase of piety, the improvement of the age, etc. And

2.Such as were typical of the promised seed, and the salvation which was to come by him.

For commandments, statutes, etc., the reader is particularly desired to refer to Lev 16:15, etc., where these things are all explained in the alphabetical order of the Hebrew words.

And Isaac dwelt in Gerar. Continued there; in this he was obedient to the command and will of God.

Genesis 26:7

gen 26:7

gen 26:7And the men of the place asked him of his wife,.... The inhabitants of Gerar inquired of Isaac who she was, whether she was his wife or not, or in what relation she stood in to him; this was not a mere civil inquiry, but what arose from the prevalence of lust in them towards her; and yet it was under some restraint, they being not so abandoned to their lusts as to exercise them upon any; not upon a man's wife, the sin of adultery being detestable to them, though that of fornication was made no account of by them:

and he said, she is my sister; herein imitating his father Abraham in his infirmity and unbelief, who in the same place had made such an answer to a like question concerning Sarah, Gen 20:1; and which if Isaac knew of, as probably he did, one would wonder that he should fall into the same evil, and especially when he had not so much to say to support his assertion as Abraham had; for Rebekah was not so near akin to him as Sarah was to Abraham; and though cousins might be called sisters, yet this was mere dissimulation to call his wife sister, and was done with an intention to deceive, and therefore not justifiable:

for he feared to say, she is my wife; which was the real truth; but the fear of men, which brings a snare, led him to this, and from which good men are not always free:

lest, said he, that is, within himself, in his own mind; and so the Targum of Jonathan, he thought in his heart:

the men of the place should kill me for Rebekah; that they might marry her, one or other of them; for, it seems, they had not so great a sense of the sin of murder, as of adultery:

because she was fair to look upon; which he feared would be a temptation to them, and stir up their impure desires after her, in order to gratify which he was afraid they would kill him; Rebekah retaining her beauty still, though she had been married in all probability forty years or more, see Gen 24:16.
