What seems here to be the singing of triumph before the victory is no matter of wonder; for our faith, as it is well known, depends not on the judgement of the flesh, nor regards what is openly evident; but it is a vision of hidden things, as it is called in Hebrews 11:1, and the substance of things not seen. As then the firmness of faith is the same, though what it apprehends is remote, and as faith ceases not to see things hidden,—for through the mirror of God’s word it ascends above heaven and earth, and penetrates into the spiritual kingdom of God,—as faith, then, possesses a view so distant, it is not to be wondered that the Prophet here boldly triumphs over the Babylonians, and now prescribes a derisive song for all nations, that the proud, who had previously with so much cruelty exalted themselves, might be scoffed at and derided.
