Jacob wrestling with the angel
Jacob wrestling with the angel or God is described in the Book of Genesis (chapter 32:22–32; also referenced in the Book of Hosea, chapter 12:3–5). The "angel" in question is referred to as "man" (אִישׁ: Ish) and "God" (אֵל: El) in Genesis, while Hosea references an "angel" (מַלְאָךְ: Malakh). The account includes the renaming of Jacob as Israel (etymologized as "contends-with-God").
In the Genesis patriarchal narrative, Jacob spent the night alone on a riverside during his journey back to Canaan. He encounters a "man" who proceeds to wrestle with him until dawn. In the end, Jacob is given the name Israel and blessed, while the "man" refuses to give his own name. Jacob then names the place where they wrestled Penuel (פְּנוּאֵל: "face of God" or "facing God").
