But let justice roll on like rivers, And righteousness like a mighty stream.
Others think that the Prophet turns aside here to celebrate the grace of Christ, which was to be made known in the gospel: and the verb יגל, igel, is rendered by many “shall be revealed;” but others more correctly derive it from the root גל, igel, to roll. Let justice then as it were, roll. But I will return to the second exposition. Most think that there is here a prediction of that righteousness which God was to make known by the coming of Christ; and some retain also the proper meaning of the verb גל, gal, to roll. They then say that the gospel is here compared to an impetuous river and a violent stream, because the Lord would rush on and penetrate through all hindrances, how many soever Satan might attempt to throw in his way. But this meaning seems not to harmonize with the Prophet’s words and is in my judgment, too refined.
