(Ex 13, 21-22) A column of fire to give them light

[21] The LORD preceded them, in the daytime by means of a column of cloud to show them the way, and at night by means of a column of fire to give them light. Thus they could travel both day and night. [22] Neither the column of cloud by day nor the column of fire by night ever left its place in front of the people.

(CCC 697) Cloud and light. These two images occur together in the manifestations of the Holy Spirit. In the theophanies of the Old Testament, the cloud, now obscure, now luminous, reveals the living and saving God, while veiling the transcendence of his glory - with Moses on Mount Sinai (Cf. Ex 24:15-18), at the tent of meeting (Cf. Ex 33:9-10), and during the wandering in the desert (Cf. Ex 40:36-38; 1 Cor 10:1-2), and with Solomon at the dedication of the Temple (Cf. 1 Kings 8:10-12). In the Holy Spirit, Christ fulfills these figures. The Spirit comes upon the Virgin Mary and "overshadows" her, so that she might conceive and give birth to Jesus (Lk 1:35). On the mountain of Transfiguration, the Spirit in the "cloud came and overshadowed" Jesus, Moses and Elijah, Peter, James and John, and "a voice came out of the cloud, saying, 'This is my Son, my Chosen; listen to him!'" (Lk 9:34-35). Finally, the cloud took Jesus out of the sight of the disciples on the day of his ascension and will reveal him as Son of man in glory on the day of his final coming (Cf. Acts 1:9; cf. Lk 21:27).
