Isaiah 1:15
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.

In context
Before · Isaiah 1:13–14
13Bring no more vain offerings. Incense is an abomination to me. New moons, Sabbaths, and convocations— I can’t stand evil assemblies. 14My soul hates your New Moons and your appointed feasts. They are a burden to me. I am weary of bearing them.
15When 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.
