The revolters are profound to make slaughter - Here may be a reference to the practice of hunters, making deep pits in the ground, and lightly covering them over, that the beasts, not discovering them, might fall in, and become a prey.
Though I have been a Rebuker - "I will bring chastisement on them all." As they have made victims of others to their idolatry, I will make victims of them to my justice. Some have thought that as many as wished to depart from the idolatrous worship set up by Jeroboam, were slaughtered; and thus Jeroboam the son of Nebat Made Israel to sin.
And the revolters are profound to make slaughter - Literally, “They made the slaughter deep,” as Isaiah says, “they deeply corupted themselves” Isaiah 31:6; and our old writers say “He smote deep.” They willed also doubtless to “make it deep,” hide it so deep, that God should never know it, as the Psalmist says of the ungodly, “that the inward self and heart of the worker‘s of iniquity is deep,” whereon it follows, that God should “suddenly wound them,” as here the prophet subjoins that God rebuked them. Actual and profuse murder has been already Hosea 4:2 mentioned as one of the common sins of Israel, and it is afterward Hosea 6:9 also charged upon the priests.
Though I have been a rebuker - Literally, “a rebuke,” as the Psalmist says, “I am prayer” Psalm 109:4, i. e., “I am all prayer.” The Psalmist‘s whole being was turned into prayer. So here, all the attributes of God, His mercies, love, justice, were concentrated into one, and that one, rebuke. Rebuke was the one form, in which they were all seen. It is an aggravation of crime to do it in the place of judgment or in the presence of the judge. Israel was immersed in his sin and heeded not, although God rebuked him continually by His voice in the law, forbidding all idolatry, and was now all the while, both in word and deed, rebuking him.
