Isaiah’s Call and Mission
6 In the year that King Uzziah died, I saw the Lord seated on a high and lofty throne, and His robe[a] filled the temple. 2 Seraphim[b] were standing above Him; each one had six wings: with two he covered his face, with two he covered his feet, and with two he flew. 3 And one called to another:
Holy, holy, holy is the Lord of Hosts;
4 The foundations of the doorways shook at the sound of their voices, and the temple was filled with smoke.
