Genesis 17:1 - Joseph Benson’s Commentary on the Old and New Testaments

And when Abram was ninety-nine years old Full thirteen years after the birth of Ishmael. So long the promise of Isaac was deferred; 1st, Perhaps to correct Abram's over-hasty marrying of Hagar. 2d, That Abram and Sarai being so far stricken in age, God's power in this matter might be the more magnified. The Lord appeared unto Abram In some visible display of his glory. And said, I am the almighty God By this name he chose to make himself known to Abram, Isaac, and Jacob, rather than by his name Jehovah, Exodus 6:3, and Genesis 35:11. And they called him by this name. It is the name of God that is mostly used throughout the book of Job, at least thirty times in the discourses of that book, in which Jehovah is used but once. After Moses, Jehovah is more frequently used, and this very rarely. I am El-shaddai. It speaks the almighty power of God, either, 1st, As an avenger, from שׁדד, he destroyed, or laid waste; a title, as some think, taken from the destruction of the old world: Or, 2d, As a benefactor, שׁ for אשׁד, who, and די, it sufficeth. Our old English translation reads it here, very significantly. I am God all-sufficient. The God with whom we have to do is self-sufficient; he hath every thing, and he needs not any thing. And he is enough to us, if we be in covenant with him; we have all in him, and we have enough in him; enough to satisfy our most enlarged desires; enough to supply the defect of every thing else, and to secure us happiness for our immortal souls. But the covenant is mutual; walk before me, and be thou perfect That is, upright and sincere. To walk before God is to set him always before us, and to think, and speak, and act in every thing as those that are always under his eye. It is to have a constant regard to his word as our rule, and to his glory as our end, in all our actions. It is to be spiritual in all the duties of religious worship, and, wholly devoted to him in all holy conversation. We must remember that this upright walking with God is the condition of our interest in his all- sufficiency. If we neglect him or dissemble with him, we forfeit the benefit of our relation to him.
