(4-7) The people (as in Isaiah 58:3-8) are rebuked for the hypocritical, or merely formal, nature of their fasts. The prophet does not, even further on, give any direct answer to their inquiry. He seems to have wished to show them that fasting or not fasting was a matter of only secondary consideration. Their fasts were undertaken on account of their sufferings; their sufferings were caused by their sins. So, then, their sins were the origin of their fasts. Let them remove sin from their midst, then fasting would be unnecessary. “All stated fasts tend to degenerate into superstition, unless there is a strong counteracting agency. The original reference to God is lost in the mere outward act.... Selfishness is the bane of all true piety, as godliness is its essence” (Moore).
