Isaiah 58:1-6 AMP

1 CRY ALOUD, spare not. Lift up your voice like a trumpet and declare to My people their transgression and to the house of Jacob their sins!

2 Yet they seek, inquire for, and require Me daily and delight [externally] to know My ways, as [if they were in reality] a nation that did righteousness and forsook not the ordinance of their God. They ask of Me righteous judgments, they delight to draw near to God [in visible ways].

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. [Lev. 16:29.]

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?

6 [Rather] is not this the fast that I have chosen: to loose the bonds of wickedness, to undo the bands of the yoke, to let the oppressed go free, and that you break every [enslaving] yoke? [Acts 8:23.]
