Verses 1-4 Many corruptions lurk out of the view of the most careful rulers. Some of the people disobeyed the express command of God, which forbade all marriages with the heathen, ( Deuteronomy 7 ) . Disbelief of God's all-sufficiency, is at the bottom of the sorry shifts we make to help ourselves. They exposed themselves and their children to the peril of idolatry, that had ruined their church and nation. Carnal professors may make light of such connexions, and try to explain away the exhortations to be separate; but those who are best acquainted with the word of God, will treat the subject in another manner. They must forebode the worst from such unions. The evils excused, and even pleaded for; by many professors, astonish and cause regret in the true believer. All who profess to be God's people, ought to strengthen those that appear and act against vice and profaneness.
Verses 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.
