Israel's last camp before Sinai (Exodus 17:1; 19:2) — the site of both the water struck from the rock at nearby Horeb and the battle with Amalek. ⚠ Its name may mean 'supports' or 'resting places,' which this chapter's own action echoes without comment: it is where Aaron and Hur physically support Moses' arms (17:12). Its exact location is unrecovered, like most of the wilderness itinerary — tradition places it in the Wadi Feiran region of the southern Sinai peninsula, a fertile oasis corridor that would explain both a nearby rock formation and Amalek's presence to defend it.
