Isaiah 1:15 in the King James Version
And when ye spread forth your hands, I will hide mine eyes from you: yea, when ye make many prayers, I will not hear: your hands are full of blood.
Context
14 My soul hates your New Moons and your appointed feasts. They are a burden to me. I am weary of bearing them.
15 When you spread out your hands, I will hide my eyes from you. Yes, when you make many prayers, I will not hear. Your hands are full of blood.
16 Wash yourselves. Make yourself clean. Put away the evil of your doings from before my eyes. Cease to do evil.
