Isaiah 1:15-17

15 "So when you spread out your hands [in prayer, pleading for My help], I will hide My eyes from you; Yes, even though you offer many prayers, I will not be listening. Your hands are full of blood!

16 "Wash yourselves, make yourselves clean; Get your evil deeds out of My sight. Stop doing evil,

17 Learn to do good. Seek justice, Rebuke the ruthless, Defend the fatherless, Plead for the [rights of the] widow [in court].
