Isaiah 43:16-17. Thus saith the Lord, which maketh a way in the sea, and a path in the mighty waters; Which bringeth forth the chariot and horse, the army and the power; they shall lie down together, they shall not rise: they are extinct, they are quenched as tow.
God, in His statement to Israel about Who He is, reminded them of how He made a path through the Red Sea, enabling them to walk across on dry land. Note, DRY land, not muddy or mucky. A firm path over dry land.
In verse 17, He described how He destroyed the Egyptian army that was trying to recapture Israel. As they followed the Israelites across the Red Sea, once all the Israelites were safely on the other side, God allowed the waters to come crashing back down over the Egyptian army, with its horses and chariots, drowning them all and destroying the might and power of Egypt.
What a dramatic scene! How horrified the Egyptian army must have been when they realized the error they had made; as their horses foundered in the rush of water, and their chariots got mired in the bottom of the sea.
