III Maccabees 6:4

4 Thou destroyedst Pharaoh, with his hosts of chariots, when that lord of this same Egypt was uplifted with lawless hardihood and loud-sounding tongue. Shedding the beams of thy mercy upon the race of Israel, thou didst overwhelm him with his proud army.

III Maccabees 6:4 In-Context

2 O king, mighty in power, most high, Almighty God, who regulatest the whole creation with thy tender mercy,
3 look upon the seed of Abraham, upon the children of the sanctified Jacob, thy sanctified inheritance, O Father, now being wrongfully destroyed as strangers in a strange land.
4 Thou destroyedst Pharaoh, with his hosts of chariots, when that lord of this same Egypt was uplifted with lawless hardihood and loud-sounding tongue. Shedding the beams of thy mercy upon the race of Israel, thou didst overwhelm him with his proud army.
5 When Sennacherim, the grievous king of the Assyrians, glorying in his countless hosts, had subdued the whole land with his spear, and was lifting himself against thine holy city, with boastings grievous to be endured, thou, O Lord, didst demolish him and didst shew forth thy might to many nations.
6 When the three friends in the land of Babylon of their own will exposed their lives to the fire rather than serve vain things, thou didst send a dewy coolness through the fiery furnace, and bring the fire upon all their adversaries.
