Matthew Poole and continuators on Exodus 14:21

21 And Moses stretched out his hand over the Sea, and the LORD caused the Sea to go back by a strong East-wind all that night, and made the sea dry land, and the waters were divided .

A proper instrument both to divide that Sea, which lay North and South, and to dry and harden the mud at the bottom of the Sea, that the Israelites might walk upon it. See Gen. 8. 13. Exod. 15. 8. Yet the Wind could never have done so great a work, especially not so speedily, if there had not been an higher, even a divine, hand to manage and improve it.

So largely that a great number of the Israelites might march in one rank, and the whole number might go a good way in it in the time here mentioned.
