Malachi 1:10

Who is - among you - From this we learn that there was not one sincere or honest priest among them. They were selfish and worldly; and so basely so, that not one of them would even kindle a fire on the hearth of the altar unless he were paid for it.

Who is there even among you? - This stinginess in God's service was not confined to those offices which cost something, as the sacrifices. Not even services absolutely costless, which required only a little trouble, as that of closing the folding-doors of the temple or the outer court, or bringing the fire to consume the sacrifices, would they do without some special hire. All was mercenary and hireling service. Others have rendered it as a wish, "who is there among you!" i. e., would that there were one among you, who would close the doors altogether; so shall ye not kindle fire on Mine altar for nought, i. e., fruitlessly! But apart from the difficulty of the construction, it is not God's way to "quench the smouldering flax." He who bids, "Gather up the fragments that remain, that nothing be lost," accepts any imperfect service rather than none. He does not break off the last link, which binds man to Himself. Then, if or when God willed His service to surcease, He would do it Himself, as He did by the destruction of the temple before the captivity, or finally by the Romans. It would have been an ungodly act (such as was only done by Ahaz, perhaps the most ungodly king of Israel) 2 Chronicles 28:24, and one which especially called down His wrath 2 Chronicles 29:8, to close the doors, and therewith to break off all sacrifice. Manasseh carried the worship of false gods into the temple itself; Ahaz, as far as in him lay, abolished the service of God. A prophet of God could not express a wish, that pious Israelites (for it is presupposed that they would do this out of zeal for God's honor) should bring the service of God to an end.

He sums up with an entire rejection of them, present and future. "I have no pleasure in you;" it is a term of repudiation , sometimes of disgust "neither will I accept an offering at your hands." He says not simply Jeremiah 6:20, "your burnt-offerings are not acceptable, nor your sacrifices sweet unto Me, but, I will not accept it." Such as they were, such they would be hereafter. God would not accept their sacrifices, but would replace them.
