After due warning, the second plague came to Egypt. Aaron stretched forth his hand over the waters of Egypt, and frogs swarmed forth. They covered every inch of land and entered the houses and bedrooms; wherever an Egyptian turned, whatever he touched, he found there the slimy bodies of frogs, the croakings of which filled the air.

Now Pharaoh became frightened, and he asked Moses and Aaron to pray to G-d to remove the nuisance, promising that he would liberate the Jewish people at once. But as soon as the frogs disappeared, he broke his promise and refused to let the children of Israel go.
