Commentaries
23:33-40 Those are miserable indeed who are forsaken and forgotten of God; and men's jesting at God's judgments will not baffle them. God had taken Israel to be a people near to him, but they shall now be cast out of his presence. It is a mark of great and daring impiety for men to jest with the words of God. Every idle and profane word will add to the sinner's burden in the day of judgment, when everlasting shame will be his portion.
39. I will … forget you—just retribution for their forgetting Him (Ho 4:6). But God cannot possibly forget His children (Isa 49:15). Rather for "forget" translate, "I will altogether lift you up (like a 'burden,' alluding to their mocking term for God's messages) and cast you off." God makes their wicked language fall on their own head [Calvin]. Compare Jer 23:36: "every man's word shall be his burden."
