Thou calledst in trouble; at the Red Sea, Exodus 14:10-12. In the secret place of thunder; from the dark and cloudy pillar, whence I thundered and fought against the Egyptians. See Exodus 13:21, Exodus 14:19,24. Others refer this to the thunder at Sinai. But at that time they were not in trouble, but in a safe and glorious condition.
