Thy way is in the sea,.... In the sea of Suph, as the Targum, the Red sea; it was the Lord that made the way in the sea for the Israelites, and went before them, and led them through it:
and thy path in the great waters; because the word rendered path is written with י yod, and is in the plural number, though the Masorites observe, that that letter is redundant, and so the word is singular; hence the Jews imagine there were more paths than one, even twelve, according to the number of the tribes, and which they think is intimated in Psalms 136:13,
and thy footsteps are not known; not by the Egyptians, who assayed to follow after the people of Israel with the Lord at the head of them, nor by any since; for the waters returned and covered the place on which the Israelites went as on dry ground; so that no footsteps or traces were to be seen at all ever since; and such are the ways God, many of them in providence as well as in grace, Romans 11:33, it may be rendered "thy heels", which made the footsteps or impressions; which latter being the works of God, may be seen and known, but not the former, he being invisible; so Gussetius e observes.
