OT § 182

See, the Lord will be seated on a light cloud and will come to Egypt and the idols of Egypt will be shaken at his presence and their heart will be worsted within them. ‘And their spirit will be troubled within them, and I will frustrate their counsel and hand Egypt over into the hands of harsh lords,’ says the Lord Sabaoth. And the Egyptians will drink water that is beside the sea, while the river will fail and be dried up. Thus says the Lord, ‘Where now are your wise men? And let them declare to you and let them say, “What has the Lord Sabaoth planned against Egypt?” On that day the Egyptians will be like women, in fear and trembling in the presence of the hand of the Lord Sabaoth, which he will bring against them. And there will be an Altar to the Lord in the country of the Egyptians and a pillar to Lord at its border. And it will be for a sign for ever to the Lord in the country of Egypt, because they will cry to the Lord and he will send them a man who will save them. And the Lord will be known to the Egyptians. And the Egyptians will know the Lord in that day, and they will offer sacrifice and gift, and they will vow vows to the Lord and pay them.
