Etymology
English from the 13th century. From firmamentum: (from firmo:, from firmus:), literally "that which strengthens or supports". The term is coined in the Vulgata in imitation of LXX στερέωμα:, which in turn translates Hebrew רקיצ:, strictly speaking a mistranslation, as the original Hebrew term meant "expanse", from the root רקצ: "to spread out", which in Syriac had acquired the meaning "to make firm or solid".
