Isaiah 58:3-5

Amplified Bible, Classic Edition

³ Why have we fasted, they say, and You do not see it? Why have we afflicted ourselves, and You take no knowledge [of it]? Behold [O Israel], on the day of your fast [when you should be grieving for your sins], you find profit in your business, and [instead of stopping all work, as the law implies you and your workmen should do] you extort from your hired servants a full amount of labor.^(A)

⁴ [The facts are that] you fast only for strife and debate and to smite with the fist of wickedness. Fasting as you do today will not cause your voice to be heard on high.

⁵ Is such a fast as yours what I have chosen, a day for a man to humble himself with sorrow in his soul? [Is true fasting merely mechanical?] Is it only to bow down his head like a bulrush and to spread sackcloth and ashes under him [to indicate a condition of heart that he does not have]? Will you call this a fast and an acceptable day to the Lord?
