Isaiah 1:12-13

“When you come to appear before Me, Who requires this of you, this trampling of My [temple] courts [by your sinful feet]? “Do not bring worthless offerings again, [Your] incense is repulsive to Me; [Your] New Moon and Sabbath [observances], the calling of assemblies— I cannot endure wickedness [your sin, your injustice, your wrongdoing] and [the squalor of] the festive assembly.
