The graceful verb נדב (nadab) connotes "an uncompelled and free movement of the will unto divine service or sacrifice," according to HAW Theological Wordbook of the Old Testament. It occurs in the Bible to indicate a volunteering for war (Judges 5:2) or other service (2 Chronicles 17:16), but most often for donating goods to the first and second temple (1 Chronicles 29:5, Ezra 1:4).
Its derivatives are:
- The feminine noun נדבה (nedaba), meaning freewill offering (Exodus 35:29, Hosea 14:5).
- The masculine noun and adjective נדיב (nadib), meaning generous or noble (Psalm 51:14, 107:40).
- The feminine version of previous noun: נדיבה (nediba), meaning generous or noble deed (Job 30:15, Isaiah 32:8).
