Exodus 14:21-22
Exodus 14:21-22 NKJV
Then 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 into dry land, and the waters were divided. So the children of Israel went into the midst of the sea on the dry ground, and the waters were a wall to them on their right hand and on their left.
