III Maccabees 6:18

18 Then the all-glorious, all-powerful, and true God, displayed his holy countenance, and opened the gates of heaven, from which two angels, dreadful of form, came down and were visible to all but the Jews.

III Maccabees 6:18 In-Context

16 Now, at the time that Eleazar had ended his prayer, the king came along to the hippodrome, with the wild beasts, and with his tumultuous power.
17 When the Jews saw this, they uttered a loud cry to heaven, so that the adjacent valleys resounded, and caused an irrepressible lamentation throughout the army.
18 Then the all-glorious, all-powerful, and true God, displayed his holy countenance, and opened the gates of heaven, from which two angels, dreadful of form, came down and were visible to all but the Jews.
19 And they stood opposite, and filled the enemies' host with confusion and cowardice; and bound them with immoveable fetters.
20 And a cold shudder came over the person of the king, and oblivion paralysed the vehemence of his spirit.
