Elijah = “Yahweh is God” (cf. 1 Kgs. 18.36, 1 Kgs. 37) is the name (surname?) of an Israelite prophet (9th century bce), and occurs 68 times in the OT (62x in 1 Kgs-2Kgs 2), 29 times in the NT and further in 1 Macc. 2.58; Sir. 48.1, Sir. 4, Sir. 12. On account of his ascension (2 Kgs. 2.11) he is considered to have been transferred to heavenly existence and accordingly his return could be expected (Mal. 3.23, Mal. 24).
