EL-ELO'HE-IS'RAEL (strength of God), the name which Jacob gave to an altar near Shechein, Gen 33:18-20; probably the place where Abraham had built an altar. Gen 12:7. The el designates God as the mighty One, able to do whatsoever he pleased. He delivered Jacob, whose other name — "Israel" — denoted his power with God.
