Malachi 1:9 - Matthew Poole's English Annotations on the Holy Bible

And now I, Malachi, pray you, O priests, beseech God that he will be gracious unto us; intercede with God for this sinful people, among which (with the modesty that is usual among God's saints) he rangeth himself; entreat they may find grace with God, and be pardoned. This detestable contempt of God, his altar, and worship, hath been by your means; you, O priests, have been great occasions of this, it is more your sin, though too much theirs; beg, then, that it may be forgiven, repent and pray, or you will not be regarded. Some think the whole verse to be an irony against those priests and their sacrifices.
