Did Pharaoh accompany his army when they went after the Israelites? If so, did he die with them?
We read in Exodus 14 that Pharaoh personally led his army against the Jews.
There are differing opinions in the Midrash concerning his fate. Some say that he drowned in the Red Sea together with his army, while others opine that he survived the miraculous event. He survived in order to retell a firsthand account of the miracles and wonders that G‑d performed.
According to one Midrash, he made his way to Nineveh, Assyria, where he became king—the same king who when hearing the prophet Jonah's message from G‑d foretelling Nineveh's destruction, encouraged all his subjects to repent in order to avert the divine decree. Apparently he had learned his lesson.
Wishing you a happy and kosher Passover!
