Isaiah 58:3, 5-9

‘Why have we fasted,’ they say, ‘and You do not see it? Why have we humbled ourselves and You do not notice?’ Hear this [O Israel], on the day of your fast [when you should be grieving for your sins] you find something you desire [to do], And you force your hired servants to work [instead of stopping all work, as the law teaches]. [Lev 16:29]

“Is a fast such as this what I have chosen, a day for a man to humble himself [with sorrow in his soul]? Is it only to bow down his head like a reed And to make sackcloth and ashes as a bed [pretending to have a repentant heart]? Do you call this a fast and a day pleasing to the LORD? “[Rather] is this not the fast which I choose, To undo the bonds of wickedness, To tear to pieces the ropes of the yoke, To let the oppressed go free And break apart every [enslaving] yoke? [Acts 8:23] “Is it not to divide your bread with the hungry And bring the homeless poor into the house; When you see the naked, that you cover him, And not to hide yourself from [the needs of] your own flesh and blood? “Then your light will break out like the dawn, And your healing (restoration, new life) will quickly spring forth; Your righteousness will go before you [leading you to peace and prosperity], The glory of the LORD will be your rear guard. [Ex 14:19, 20; Is 52:12] “Then you will call, and the LORD will answer; You will cry for help, and He will say, ‘Here I am.’ If you take away from your midst the yoke [of oppression], The finger pointed in scorn [toward the oppressed or the godly], and [every form of] wicked (sinful, unjust) speech, [Ex 3:14]
