Shittah (singular) and shittim (plural) name the acacia tree, almost certainly the Acacia nilotica or Acacia seyal that thrives in the arid wadis of Sinai and the Negev. Of its 28 occurrences, 26 appear in the Priestly tabernacle instructions of Exodus 25-38, where 'acacia wood' (atsei shittim) is the specified material for the ark of the covenant, the table of showbread, the altars of burnt offering and incense, the supporting frames and poles, and the pillars at the entrance (Exod 25:10, 13, 23, 28; 26:15, 26, 32; 27:1, 6; 30:1, 5). Deuteronomy 10:3 recalls Moses making the ark of shittim wood. The sole non-constructional use is Isaiah 41:19, where God promises to plant the shittah alongside cedar, myrtle, and olive in the desert — a sign of eschatological transformation. All target languages transliterate or use the botanical equivalent: Spanish 'acacia,' French 'acacia,' German 'Akazie.'
