Elishama (אֱלִישָׁמָע) combines El (God) and shama (to hear, listen, obey). The name means "God has heard" or "My God hears." Multiple OT individuals bear this name, including a son of David, a scribe in Jehoiakim's court, and a leader of Ephraim in the wilderness.
The divine attribute of hearing (shama) is central to Israel's covenant theology. God hears the cries of His people — this is the testimony of Hagar (Genesis 16:11), Hannah (1 Samuel 1), Israel in Egypt (Exodus 2:24). The name Elishama confesses this. The root shama also gives us the Shema (Deuteronomy 6:4): "Hear, O Israel." The God who hears demands to be heard. Elishama the scribe kept Jeremiah's scroll in his chamber — a fitting role for one whose name declares that God listens.
