(19) Are not known.--"We know not, they knew not, by what precise means the deliverance was wrought; we know not by what precise track through the gulf the passage was effected. We know not; we need not know. The obscuring, the mystery, here as elsewhere, was part of the lesson. . . . All that we see distinctly is, that through this dark and terrible night, with the enemy pressing close behind, and the driving sea on either side, He led His people like sheep by the hand of Moses and Aaron" (Stanley, Jewish Church, i. 128).

To some minds the abruptness of the conclusion of the psalm marks it as unfinished. But no better end could have been reached in the poet's perplexity than that to which he has been led by his musings on the past, the thought of the religious aids ready to his hand, in the faith and worship left by Moses and Aaron. We are reminded of him who recalled the thoughts of the young man, searching for a higher ideal of duty, back to the law and obedience. Or if the psalm is rather an expression of the feeling of the community than of an individual, there is a pointed significance in the conclusion given to all the national cries of doubt and despair--the one safe course was to remain loyal and true to the ancient institutions.

Verse 19. - Thy way is in the sea; rather, was in the sea. Thou wentest, i.e., in person before thy people in their passage across the dry bed of the Red Sea; truly there, though invisible (comp. Exodus 15:13; Psalm 78:52, 53; Psalm 106:9; Isaiah 63:13). And thy path in the great waters; literally, thy paths. So the Revised Version. And thy footsteps are not known; rather, were not. No one perceived thy presence, much less discerned thy footsteps. As in external nature and in the human heart, God worked secretly.

77:11-20 The remembrance of the works of God, will be a powerful remedy against distrust of his promise and goodness; for he is God, and changes not. God's way is in the sanctuary. We are sure that God is holy in all his works. God's ways are like the deep waters, which cannot be fathomed; like the way of a ship, which cannot be tracked. God brought Israel out of Egypt. This was typical of the great redemption to be wrought out in the fulness of time, both by price and power. If we have harboured doubtful thoughts, we should, without delay, turn our minds to meditate on that God, who spared not his own Son, but delivered him up for us all, that with him, he might freely give us all things.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 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 Psalm 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.
