Isaiah 58:1-3

“Cry aloud, do not hold back; Lift up your voice like a trumpet, And declare to My people their transgression And to the house of Jacob their sins. “Yet they seek Me day by day and delight [superficially] to know My ways, As [if they were in reality] a nation that has done righteousness And has not abandoned (turned away from) the ordinance of their God. They ask of Me righteous judgments, They delight in the nearness of God. ‘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]
