Verse 6. - I am ashamed and blush. Jeremiah had complained that in his day those who "committed abominations were not at all ashamed, neither could they blush" (Jeremiah 6:15; Jeremiah 8:12). Ezra, with these words in his thoughts possibly, begins his confession with a protestation that he at any rate is not open to this reproach - he blushes and burns with shame for the sins of his people. Our iniquities are increased over our head. i.e. have kept on rising like a flood; "gone over our head" (Psalm 38:4), and overwhelmed us. And our trespass is grown up unto the heavens. Has grown to such a height that it has attracted the notice of God, and made him angry with us.

9:5-15 The sacrifice, especially the evening sacrifice, was a type of the blessed Lamb of God, who in the evening of the world, was to take away sin by the sacrifice of himself. Ezra's address is a penitent confession of sin, the sin of his people. But let this be the comfort of true penitents, that though their sins reach to the heavens, God's mercy is in the heavens. Ezra, speaking of sin, speaks as one much ashamed. Holy shame is as necessary in true repentance as holy sorrow. Ezra speaks as much amazed. The discoveries of guilt cause amazement; the more we think of sin, the worse it looks. Say, God be merciful to me sinner. Ezra speaks as one much afraid. There is not a surer or saddler presage of ruin, than turning to sin, after great judgments, and great deliverances. Every one in the church of God, has to wonder that he has not wearied out the Lord's patience, and brought destruction upon himself. What then must be the case of the ungodly? But though the true penitent has nothing to plead in his own behalf, the heavenly Advocate pleads most powerfully for him.And said, O my God,.... Here begins the prayer of Ezra, and that with faith in God as covenant God, even when he was about to make confession of sin, and repentance for it; that prayer is right which is put up in faith, and that repentance genuine which is accompanied with faith, and flows from it:

I am ashamed, and blush to lift up my face to thee, my God; a true sight and sense of sin causes shame and blushing, and never more than when a man is sensible of his covenant interest in God, and of his grace and favour to him, particularly in the forgiveness of his sin, see Ezekiel 16:61

for our iniquities are increased over our head; arisen and swelled like mighty waters, which seemed to threaten an overwhelming of them:

and our trespass is grown up unto the heavens; being done in an open, public, and insolent manner, and in such numbers, that they were, as it were, piled up in heaps, reaching to heaven, and calling down vengeance from thence. Ezra includes himself as being one of the same nation; and these sins being so common were become national ones, which involved all the individuals, and exposed them to the divine resentment.
