This is an affirmative question, "Shall they therefore;" which, however, requires a negative answer. Then all interpreters are mistaken; for they think that the Prophet here complains, that he presently extends his net after having made a capture, but he rather means, "Is he ever to extend his net?" that is, "How long, O Lord, wilt thou permit the Assyrians to proceed to new plunders, so as to be like the hunter, who after having taken a boar or a stag, is more eager, and immediately renews his hunting; or like the fisherman, who having filled his little ship, with more avidity pursues his vocation? Wilt thou, Lord, he says, suffer the Assyrians to become more assiduous in their work of destruction?" And he shows how unworthy they were of God's forbearance, for they slew the nations. "I speak not here," he says, "either of fish or of any other animal, nor do I speak of this or that man, but I speak of many nations. As these slaughters are thus carried on through the whole world, how long, Lord, shall they be unpunished? for they will never cease." We now see the purport of the Prophet's complaint; but we shall find in the next lecture how he recovers himself.

Shall they therefore empty their net, and not spare continually to slay the nations? - The prophet, like Isaiah Isaiah 18:4-5, stands at the very last point, before the fury and desire of the enemy was fulfilled. People, like fish, were gathered together for a prey; he who had taken them was rejoicing and exulting beforehand in his booty; his portion and meat were the choice of the earth; the prophet leeks on, as it were, and beholds the net full; there is but one step more; "Shall he empty it? Shall he then devour those whom he has caught? and so cast his emptied net again unceasingly, pitilessly, to slay the nations?" This question he answers in the next chapter - A Deliverer will come!

And not spare continually to slay the nation? - They are running from conquest to conquest; burning, slaying, sacking, and slaughtering. Like the fishermen, who throw cast after cast while any fish are to be caught, so Nebuchadnezzar is destroying one nation after another. This last sentence explains the allegory of the net.

Shall they therefore empty their net, and not spare continually to slay (n) the nations?
(n) Meaning, that they would not.

Shall they therefore empty their net,.... Or "thus", after this manner, so Noldius; as fishermen do, when they have had a good cast, and a large draught, spread the net, and take out the fishes, in order to throw it again, and catch more; and so it is asked, should these Chaldeans, when they have conquered one nation, and so filled their net or themselves with the spoil, carry it to Babylon, and there lay it up, and then proceed to fight against another kingdom and nation, and plunder it in like manner?
and not spare continually to slay the nations? the inhabitants of them one after another, and subdue them under them, and make themselves master of all their treasure, until they are arrived to universal monarchy by such cruel and unmerciful methods. The Targum is,
"shall he send his armies continually to consume nations, and that without mercy?''
This the prophet proposes in the name of the whole body of the Lord's people, and leaves it with him to have an answer to it, which is given in the following chapter Habakkuk 2:1.

Shall they . . . empty their net?--Shall they be allowed without interruption to enjoy the fruits of their violence?
therefore--seeing that they attribute all their successes to themselves, and not to Thee. The answer to the prophet's question, he by inspiration gives himself in the second chapter.

Empty their net - As fisher - men empty the full net to fill it again.
