Genesis 32:24 - Joseph Benson’s Commentary on the Old and New Testaments

Jacob was left alone In some private place, that he might more freely and ardently pour out his soul in prayer, and again spread his cares and fears before God. There wrestled a man with him The eternal Word, or Son of God, who often appeared in a human shape, before he assumed the human nature. We are told by Hosea 12:4, how Jacob wrestled with him; He wept and made supplication: prayers and tears were his weapons. It was not only a corporal but a spiritual wrestling, by vigorous faith and holy desire; and this circumstance shows that the person with whom he wrestled was not a created angel, but the angel of the covenant; for surely he would not pray and make supplication to a creature. Indeed, in the passage just referred to, Hosea terms him Jehovah, God of hosts, and says, Jehovah is his memorial.
