When thou passest through the waters, &c.— The general sense of the promise in this verse is, that God will so support and protect his spiritual church in those adversities and calamities which seem to threaten its destruction, that it shall never be destroyed; and that true believers shall always be supported by the hand of the Almighty. The expression in this verse seems to allude to some preceding events in the Jewish history, and to have respect to some succeeding ones. See Psalms 66:12.
