21 See, the Lord is coming out of his dwelling to punish the people of the earth for their sins. The earth will disclose the blood shed on it; the earth will conceal its slain no longer.
21 For behold, the Lord is coming out from his place to punish the inhabitants of the earth for their iniquity, and the earth will disclose the blood shed on it, and will no more cover its slain.
21 Because God is sure to come from his place to punish the wrong of the people on earth. Earth itself will point out the bloodstains; it will show where the murdered have been hidden away.
21 For behold, the Lord comes out of His place To punish the inhabitants of the earth for their iniquity; The earth will also disclose her blood, And will no more cover her slain.
21 Look! The Lord is coming from heaven to punish the people of the earth for their sins. The earth will no longer hide those who have been killed. They will be brought out for all to see.
Matthew Henry's Commentary on Isaiah 26:21
Commentary on Isaiah 26:20-21
(Read Isaiah 26:20-21)
When dangers threaten, it is good to retire and lie hid; when we commend ourselves to God to hide us, he will hide us either under heaven or in heaven. Thus we shall be safe and happy in the midst of tribulations. It is but for a short time, as it were for a little moment; when over, it will seem as nothing. God's place is the mercy-seat; there he delights to be: when he punishes, he comes out of his place, for he has no pleasure in the death of sinners. But there is hardly any truth more frequently repeated in Scripture, than God's determined purpose to punish the workers of iniquity. Let us keep close to the Lord, and separate from the world; and let us seek comfort in secret prayer. A day of vengeance is coming on the world, and before it comes we are to expect tribulation and suffering. But because the Christian looks for these things, shall he be restless and dismayed? No, let him repose himself in his God. Abiding in him, the believer is safe. And let us wait patiently the fulfilling of God's promises.
