(1.) Here is a use of information. From what passed between God and Jacob we may learn that Jehovah, the Lord God of hosts, is the God of Israel; he was the God of Jacob, and this is his memorial throughout all the generations of the seed of Jacob (v. 5)—the more shame for those who forgot the memorial of their church, deserted the God of their fathers, and exchanged a Lord of hosts for Baalim. Note, Those only are accounted the people of God that keep up a memorial of God, such a memorial of him as he himself has instituted, by which he makes himself known and will have us to remember him. Here are two memorials of his, by which he is distinguished from all others, and is to be acknowledged and adored by us. [1.] The former denotes his existence of himself. He is Jehovah, much the same with I AM, the same that was, and is, and is to come, infinite, eternal, and unchangeable. Jehovah is his memorial, his peculiar name. [2.] The latter denotes his dominion over all: He is the God of hosts, that has all the hosts of heaven and earth at his beck and command, and makes what use he pleases of them. Jacob saw Mahanaim—God's two hosts, about the time that he wrestled with the angel (Gen. xxxii. 1, 2), and so learned to call God the God of hosts, and transmitted it to us as his memorial. God's names, titles, and attributes, are the memorials of him; there is no need for images to be such. And that which was a revelation of God to one is his memorial to many, to all generations.
