A compound divine name combining YHWH with nes (banner/standard, H5251). Moses erected an altar with this name after Israel's victory over Amalek at Rephidim, where Joshua's armies prevailed as long as Moses held his staff high before the LORD. The nes was a military standard or rallying pole — a visible signal of divine presence and authority.
YHWH Nissi declares that God Himself is the rallying point of His people's warfare. Israel did not win by superior strength but by lifting eyes to the LORD. This name echoes throughout Scripture's warfare theology: the battle belongs to God (1 Samuel 17:47), and those who fight under His banner are guaranteed ultimate victory. Christ is the ultimate banner lifted up (Isaiah 11:10; John 3:14–15) — drawing all people to Himself and signaling God's triumph over sin and death.
