II. She engaged them to take her and her relations under their protection, that they might not perish in the destruction of Jericho, v. 12, 13. Now, 1. It was an evidence of the sincerity and strength of her faith concerning the approaching revolution in her country that she was so solicitous to make an interest for herself with the Israelites, and courted their kindness. She foresaw the conquest of her country, and in the belief of that bespoke in time the favour of the conquerors. Thus Noah, being moved with fear, prepared an ark to the saving of his house, and the condemning of the world, Heb. xi. 7. Those who truly believe the divine revelation concerning the ruin of sinners, and the grant of the heavenly land to God's Israel, will give diligence to flee from the wrath to come, and to lay hold of eternal life, by joining themselves to God and to his people. 2. The provision she made for the safety of her relations, as well as for her own, is a laudable instance of natural affection, and an intimation to us in like manner to do all we can for the salvation of the souls of those that are dear to us, and, with ourselves, to bring them, if possible, into the bond of the covenant. No mention is made of her husband and children, but only her parents, and brothers, and sisters, for whom, though she was herself a housekeeper, she retained a due concern. 3. Her request that they would swear unto her by Jehovah is an instance of her acquaintance with the only true God, and her faith in him and devotion towards him, one act of which is religiously to swear by his name. 4. Her petition is very just and reasonable, that, since she had protected them, they should protect her, and since her kindness to them extended to their people, for whom they were now negotiating, their kindness to her should take in all hers. It was the least they could do for one that had saved their lives with the hazard of her own. Note, Those that show mercy may expect to find mercy. Observe, She does not demand any preferment by way of reward for her kindness to them, though they lay so much at her mercy that she might have made her own terms, but only indents for her Life, which in a general destruction would be a singular favour. Thus God promised Ebed-Melech, in recompence for his kindness to Jeremiah, that in the worst of times he should have his life for a prey, Jer. xxxix. 18. Yet this Rahab was afterwards advanced to be a princess in Israel, the wife of Salmon, and one of the ancestors of Christ, Matt. i. 5. Those that faithfully serve Christ and suffer for him he will not only protect, but prefer, and will do for them more than they are able to ask or think.
