Bring your worthless offerings no more; your incense is detestable to Me – your New Moons, Sabbaths, and convocations. I cannot endure iniquity in a solemn assembly.

I hate your New Moons, and your appointed feasts. They have become a burden to Me; I am weary of bearing them.

When you spread out your hands in prayer, I will hide My eyes from you; even though you multiply your prayers, I will not listen.

Your hands are covered with blood. Wash and cleanse yourselves. Remove your evil deeds from My sight.

Stop doing evil! Learn to do right; seek justice and correct the oppressor. Defend the fatherless and plead the case of the widow.

Isaiah 1:13-17
