First Reading · Isaiah 48:17-19

17Thus saith the Lord thy redeemer, the Holy One of Israel: I am the Lord thy God that teach thee profitable things, that govern thee in the way that thou walkest.18O that thou hadst hearkened to my commandments: thy peace had been as a river, and thy justice as the waves of the sea,19And thy seed had been as the sand, and the offspring of thy bowels like the gravel thereof: his name should not have perished, nor have been destroyed from before my face.

commentary

The strangest thing in these three verses is the tense. God introduces himself in the present — I am the Lord thy God that teach thee profitable things, that govern thee in the way that thou walkest (v. 17) — and then, without warning, switches to a wish about a past that can no longer be altered: O that thou hadst hearkened to my commandments (v. 18). What follows is not a promise but an inventory of what would have been. Peace like a river, justice like the waves of the sea, descendants as numberless as sand and as the gravel of the shore. The two water images are not interchangeable: a river runs steadily and never runs out, while the surf is sheer unstoppable force. Israel is being shown, in some detail, a life it did not live.

The Catholic commentary the pipeline holds for this passage is a single line, and it falls on the last clause. Where the text says his name should not have perished, nor have been destroyed from before my face (v. 19), Haydock observes that the Jews were not forgotten until they had rejected the Messias. That is a deliberate narrowing of the threat. Exile did not cut the name off; the losses catalogued here are real but recoverable, and the sentence stays open long past the date of the prophecy. What finally closes it, in Haydock's reading, is not disobedience in general but a refusal offered to a particular person — which means the passage's grief is not archival. The wish O that thou hadst hearkened is still being spoken over people who can still hearken.

A Protestant Perspective

Matthew Henry hears the whole oracle as God's own answer to the charge that he afflicts willingly. The same voice that gave the law wished the people obedient — O that there were such a heart in them — and now, having punished them, wishes it again; which Henry takes as proof, confirmed by oath elsewhere, that God has no pleasure in the death of sinners. He reads the title in v. 17 as doing double duty: I am the Lord thy God introduces the law and gives it authority, and the identical words introduce the promise and make it good. Whom God redeems, he first teaches — and teaches by the affliction itself, so that deliverance from trouble is preceded by profit taken from trouble.

On the catalogue of forfeited blessings Henry is unsparing about why it is recited at all. It is set down so that the people may be humbled by measuring what sin cost them, and he presses the point: sin deserves our anger because it robs us not only of what we had but of what God was holding for us, and the misery of the disobedient is made worse by the thought of how happy they might have been. Jamieson, Fausset and Brown sharpen the philology behind the images — the river is the standing symbol of blessing flowing from God's throne, and like the gravel thereof they would render, with the Hebrew, "like that of its bowels," the teeming life of the sea rather than its shingle, though they concede that Jerome, the Chaldee and the Syriac support the familiar version. Both notice that the name is cut off only as a nation, and that the prophecy therefore keeps looking forward.
