Elyaqim (אֶלְיָקִים) combines El (God) and qum (to rise, stand, establish). The name means "God will raise up" or "God will establish." It belongs to theophoric names declaring God's sovereign action. Multiple OT individuals bear this name; most significantly, Isaiah 22:20 applies it in a messianic context.
Isaiah 22:20–22 presents Eliakim son of Hilkiah as a type of the Messiah — one whom God raises up, on whom the key of David is placed, who opens and no one shuts. This typology is applied to Jesus in Revelation 3:7: "These are the words of him who is holy and true, who holds the key of David." The name thus becomes prophetically significant: what Elyaqim did for the household of David, Christ does for the household of God. The man also served as governor under Hezekiah, mediating between the Assyrian threat and God's people — another shadow of Christ's mediatorial office.
