Make thy seed as the sand - Having come to the promise by which the covenant was ratified both to Abraham and Isaac, he ceased, his faith having gained strong confirmation in a promise which he knew could not fail, and which he found was made over to him, as it had been to his father and grandfather.

And thou saidst, I will surely do thee good,.... All kind of good, most certainly and constantly; so Jacob rightly interpreted the promise, "I will be with thee", Genesis 31:3; for the promise of God's presence includes and secures all needful good to his people; and from this general promise Jacob draws an argument for a special and particular good, the preservation of him and his family, he was now pleading for; and the rather he might hope to succeed, since the following promise was also made him:

and make thy seed as the sand of the sea, which cannot be numbered for multitude; which could not be fulfilled, if he and his family were cut off at once, as he feared; but God is faithful who has promised.

"For I am in fear of him, that (פּן ne) he come and smite me, mother with children." בּנים על אם is a proverbial expression for unsparing cruelty, taken from the bird which covers its young to protect them (Deuteronomy 22:6, cf. Hosea 10:14). על super, una cum, as in Exodus 35:22.

And thou saidst, I will surely do thee good, and make thy seed as the sand of the sea, which cannot be numbered for multitude.

32:12 Thou saidst, I will surely do thee good - The best we can say to God in prayer is, what he hath said to us. God's promises as they are the surest guide of our desires in prayer, and furnish us with the best petitions, so they are the firmest ground of our hopes, and furnish us with the best pleas. Thou saidst, I will do thee good - Lord, do me good in this matter. He pleads also a particular promise, that of the multiplying of his seed. Lord, what will become of that promise, if they be all cut off?

32:9-23 Times of fear should be times of prayer: whatever causes fear, should drive us to our knees, to our God. Jacob had lately seen his guards of angels, but in this distress he applied to God, not to them; he knew they were his fellow-servants, Re 22:9. There cannot be a better pattern for true prayer than this. Here is a thankful acknowledgement of former undeserved favours; a humble confession of unworthiness; a plain statement of his fears and distress; a full reference of the whole affair to the Lord, and resting all his hopes on him. The best we can say to God in prayer, is what he has said to us. Thus he made the name of the Lord his strong tower, and could not but be safe. Jacob's fear did not make him sink into despair, nor did his prayer make him presume upon God's mercy, without the use of means. God answers prayers by teaching us to order our affairs aright. To pacify Esau, Jacob sent him a present. We must not despair of reconciling ourselves to those most angry against us.
