44:20-30 Whatever evil comes upon us, it is because we have sinned against the Lord; we should therefore stand in awe, and sin not. Since they were determined to persist in their idolatry, God would go on to punish them. What little remains of religion were among them, would be lost. The creature-comforts and confidences from which we promise ourselves most, may fail as soon as those from which we promise ourselves least; and all are what God makes them, not what we fancy them to be. Well-grounded hopes of our having a part in the Divine mercy, are always united with repentance and obedience.

29. this … sign unto you—The calamity of Pharaoh-hophra (see on [970]Jer 44:30) shall be a sign to you that as he shall fall before his enemy, so you shall subsequently fall before Nebuchadnezzar (Mt 24:8) [Grotius]. Calvin makes the "sign" to be simultaneous with the event signified, not antecedent to it, as in Ex 3:12. The Jews believed Egypt impregnable, so shut in was it by natural barriers. The Jews being "punished in this place" will be a sign that their view is false, and God's threat true. He calls it "a sign unto you," because God's prediction is equivalent to the event, so that they may even now take it as a sign. When fulfilled it would cease to be a sign to them: for they would be dead.
