4:21,22 Here it is foretold that an end should be put to Zion's troubles. Not the fulness of punishment deserved, but of what God has determined to inflict. An end shall be put to Edom's triumphs. All the troubles of the church and of the believer will soon be accomplished. And the doom of their enemies approaches. The Lord will bring their sins to light, and they shall lie down in eternal sorrow. Edom here represents all the enemies of the church. And the corruption, and sin of Israel, which the prophet has proved to be universal, justifies the judgments of the Lord. It shows the need of that grace in Christ Jesus, which the sin and corruption of all mankind make so necessary.

discover—By the severity of His punishments on thee, God shall let men see how great was thy sin (Jer 49:10). God "covers" sin when He forgives it (Ps 32:1, 5). He "discovers," or "reveals," it, when He punishes it (Job 20:27). Jer 49:10 shows that Margin is wrong, "carry captive" (this rendering is as in Na 2:7; compare "discovered," Margin).
