According to Kent Brown, in an obvious coloration from the Exodus story, Amulon is usually mentioned in the phrase "Amulon and his brethren" (Mosiah 23:34-35; 24:1; 25:12; Alma 25:4, 8; cf. Mosiah 24:4-5), who stand as substitutes for "Pharaoh and his people" whom God punishes;, even their children eventually being slain (see Exodus 12:29-30; Alma 25:4, 8). On the opposite side stands "Alma and his brethren" (Mosiah 23:35-37; 24:8, 15) or "Alma and his people" (Mosiah 24:12, 17-18, 20, 23), who recall "Moses and his people" whom the Lord delivers from bondage by leading them "into the wilderness," onto God's path, all preparations having been made the previous night (Exodus 12:1-13, 21-23; and Mosiah 24:18-20). (See David Daube, The Exodus Pattern in the Bible, London: Faber and Faber, 1963, 73.)
On the other hand, in a source with a decided Lamanite connection, Amulon and his followers are routinely called "Amulonites" (Alma 21:3-4; 23:14; and 24:1, 28-29). In one passage, one finds the phrase "the people of Amulon" (Alma 21:2), which seems to designate this group before it became well established. [S.
