I saw the Lord sitting upon a throne, high and lifted up; and his train filled the temple. Above him stood the seraphim; each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew. And one called to another and said: "Holy, holy, holy is the Lord of hosts; the whole earth is full of his glory." And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. And I said: "Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts!" Then flew one of the seraphim to me, having in his hand a burning coal which he had taken with tongs from the altar.

Peter delivered from prison by an angel (Acts 12,1-19)

Peter was sleeping between two soldiers, bound with two chains, and sentries before the door were guarding the prison; and behold, an angel of the Lord appeared, and a light shone in the cell; and he struck Peter on the side and woke him, saying, "Get up quickly." And the chains fell off his hands. And the angel said to him, "Dress yourself and put on your sandals." And he did so. And he said to him, "Wrap your mantle around you and follow me." And he went out and followed him; he did not know that what was done by the angel was real, but thought he was seeing a vision. When they had passed the first and the second guard, they came to the iron gate leading into the city. It opened to them of its own accord, and they went out and passed on through one street [...]
