(2.) They multiplied their sacrifices, v. 13. Their altars were smoking altars: They sacrificed flesh for the sacrifices of God's offerings, and they celebrated their feasts upon their sacrifices; they were at a great expense upon their devotions, and (as those commonly are who set up their own inventions in the room of divine institutions) were very zealous in their way; as if they hoped by their impositions on themselves to atone for the contempt of the great atonement, and by their observing a ceremonial law of their own to excuse themselves from the obligation of all God's moral precepts. But how did they speed? [1.] God makes no reckoning of their services: The Lord accepts them not. How should he, when they did not offer their sacrifice upon that altar which alone sanctified the gift, and when they only sacrificed flesh, but not the spiritual sacrifice of a penitent believing heart? Note, Those services only are acceptable to God which are performed according to the rule of his word, and through Jesus Christ, 1 Pet. ii. 5. [2.] He takes that occasion to reckon with them for their sins; now will he, instead of pardoning their iniquity and blotting out their sins, as they expected, remember their iniquity and visit their sins. Such an abomination to the Lord are the sacrifices of the wicked that they provoke him to call them to an account for all their other abominations. When they think by their sacrifices to bribe the Judge of heaven and earth into a connivance at their wickedness he will resent that as the highest affront they can put upon him, and it shall be the measure-filling sin. Note, A petition for leave to sin amounts to an imprecation of the curse for sin, and so it shall be answered, according to the multitude of the idols. "I will punish their sins, for they shall return to Egypt;" they shall be carried captive into Assyria, which shall be to them a house of bondage, as Egypt was to their fathers. Or it refers to Deut. xxviii. 68, where returning to Egypt is made to close and complete the miseries of that sinful nation.
