Esaïe 1:13-15
13
Bring no more vain oblations; incense is an abomination unto me; the new moons and sabbaths, the calling of assemblies, I cannot away with; it is iniquity, even the solemn meeting.
14
Your new moons and your appointed feasts my soul hateth: they are a trouble unto me; I am weary to bear them.
15
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.
