thy path in the great waters] That is, in deep waters.
thy foot-steps are not known] For when thou hadst brought over thy people, the water returned to her course: and the enemies that thought to have followed them, could not passe thorow, Exodus 14:28-29. Hence it appears that this parting of the sea, was not from any naturall cause, or accident, but wrought by God of purpose, that his people might passe thorow the sea.
