6:1-7 Those are looked upon as doing well for themselves, who do well for their bodies; but we are here told what their ease is, and what their woe is. Here is a description of the pride, security, and sensuality, for which God would reckon. Careless sinners are every where in danger; but those at ease in Zion, who are stupid, vainly confident, and abusing their privileges, are in the greatest danger. Yet many fancy themselves the people of God, who are living in sin, and in conformity to the world. But the examples of others' ruin forbid us to be secure. Those who are set upon their pleasures are commonly careless of the troubles of others, but this is great offence to God. Those who placed their happiness in the pleasures of sense, and set their hearts upon them, shall be deprived of those pleasures. Those who try to put the evil day far from them, find it nearest to them.

invent … instruments … like David—They fancy they equal David in musical skill (1Ch 23:5; Ne 12:36). They defend their luxurious passion for music by his example: forgetting that he pursued this study when at peace and free from danger, and that for the praise of God; but they pursue for their own self-gratification, and that when God is angry and ruin is imminent.
