Important Words:

طود (mountain) is derived from طاد which means, it was or became firm or steadfast. طود means, a mountain or a great mountain rising high into the sky, an elevated or overlooking tract of land (Lane & Aqrab).

فرق (part) is derived from فرق (faraqa) and means, a piece or portion that is split or separated from a thing; a great flock or herd of sheep or goats only; a group of boys; a mountain; a wave, billow or surge (Lane & Aqrab).

Commentary:

For a more detailed discussion as to how the Israelites passed safely through the sea and how Pharaoh with his hosts was drowned, see 20:78

The idea embodied in the words اضرب بعصاک الحجر has been expressed elsewhere (20:78) in the words فاضرب لھم طریقا فی البحر یبساi.e. "make for them a dry path in the sea." God miraculously so arranged that when the Israelites were crossing the sea it was the time of the low tide and the water of the sea had receded, leaving a dry path for them to pass. But when the Egyptians following them reached the middle of the sea, the high tide returned and the rising water quickly engulfed them.

The words کل فرق may either refer to the two parties of the Egyptians and the Israelites or to the several parties in which the Egyptians might have become divided while they were crossing the sea; or they may refer to each wave of the sea because when the water was receding it looked like a huge mound.
