The name Ulam is borne by two men in the Old Testament genealogies: (1) a descendant of Manasseh (1 Chronicles 7:16–17), and (2) a descendant of Benjamin through Eshek, noted as a skilled archer (1 Chronicles 8:39–40). The name connects to ulam (vestibule/strength).
The Benjaminite Ulam is specifically noted for having sons and grandsons who were "brave warriors and skilled archers" — a detail that connects Benjamin's martial heritage (Genesis 49:27 compares Benjamin to a ravenous wolf) with practical military skill. The genealogical attention to skilled archers reflects the ancient conviction that gifts and abilities are providentially given and should be cultivated in service of God's people.
