“... Relation to the canonical books OLD TESTAMENT The mystics were steeped in the Bible and their picture of the heavenly world was formed by harmonizing the Old Testament references to (1) theophanies, (2) angels, and (3) ascensions to heaven. 1. Theophanies: The visions of the Merkabah in Ezekiel 1; 3:12-15, 22-24; 8:1-4; 10:1-22; and 43:1-7 were their basic texts. These provided them with such fundamental elements as the Merkabah (3En 1:1, 5-7); the wheels (ophanim; 3En 25); the four creatures (hayyot; 3En 20f.); the throne of glory (3En 1:10,12); the hasmal (3En 36:2,7); the cherubim (3En 22). Daniel 7:9-10 and Isaiah 6 were incorporated into Ezekiel's picture. Daniel 7 records a vision of God seated on a fiery throne which has wheels of flame. It furnishes the additional motifs of the heavenly law court (3En 28:7), the River of Fire (3En 18:19-21; 19:4; 33:4; 36:1-2; 37:1), and the hosts of attendant angels (cf. 3En 19:6). Isaiah 6 contains a vision of God seated on a high and exalted throne (cf. 3En 26:12). Isaiah 6 contributes to the total picture the seraphim (3En 26) and the QeduSSah (3En 1:12; 20:2). Note also the vision of heaven in 1 Kings 22:19-22, in which the Lord is seen seated on his throne with all the array of heaven standing before him. Ezekiel employs the language of the nature theophanies ("fire, lightning, storm") to express the appearance of God's glory. The Merkabah texts expand this imagery by drawing on other Old Testament accounts of nature theophanies, particularly God's appearance to Israel at Sinai (Ex 19:16-18; cf. IKgs 19:11- 13; Pss 18:7-15 and 97:2-5). For combinations of these elements see 3 Enoch 34 and 37. ...”
