Isaiah 58:2-4

New Revised Standard Version, Anglicised

² Yet day after day they seek me
    and delight to know my ways,
as if they were a nation that practised righteousness
    and did not forsake the ordinance of their God;
they ask of me righteous judgements,
    they delight to draw near to God.
³ ‘Why do we fast, but you do not see?
    Why humble ourselves, but you do not notice?’
Look, you serve your own interest on your fast-day,
    and oppress all your workers.
⁴ Look, you fast only to quarrel and to fight
    and to strike with a wicked fist.
Such fasting as you do today
    will not make your voice heard on high.
