This verb appears only once in the Hebrew Bible, in Moses's Song where he rebukes Israel for forgetting God. The word is textually complex—appearing in an apocopated imperfect form—and ancient versions differ. The Samaritan Pentateuch reads differently, and scholars debate whether this represents the root meaning 'forget' or comes from another root entirely. Deuteronomy 32:18 uses striking imagery: 'the Rock who begat you, you forgot,' making divine amnesia a profound act of covenant betrayal. The multilingual glosses consistently render this as forgetting, supporting the traditional understanding despite textual difficulties.
