Dathan in the Bible Encyclopedia - ISBE

da'-than (dathan, meaning and derivation unknown, though the name is found in Assyrian, in the records of Shalmaneser II): The son of Eliab the son of Pallu the son of Reuben (Nu 26:5 ff; Dt 11:6; Ps 106:17). He and his brother Abiram, with others, followed Korah the Levite in disputing the authority of Moses and Aaron in the wilderness (Nu 16-17; 26; Dt 11:6; Ps 106:17). Other followers of Korah perished by fire before the tent of meeting, but Dathan and Abiram were swallowed up by the earth, with their families and their goods, at their tents.
