"Go to Bethel, and sin; To Gilgal, and sin more. Bring your sacrifices every morning, Your tithes every three days,
"For this pleaseth you ..." The ancient Israelites had fallen into the error of supposing that whatever was pleasing and acceptable to themselves was allowable in the worship of God. Many moderns are blinded by the same delusion.  The determinative factor regarding what is, or is not, acceptable to God in his worship is the fact of whether or not God has commanded whatever actions, sacrifices, etc., are offered.  The proposition that God has no concern with regard to "how" he is worshipped by men is refuted on every page of the Bible.  Cain was condemned for violating God's prescription for worship; and, both in that instance, and here, there is no way to limit God's displeasure to prior social injustice on the part of the worshipper.  And why do men do otherwise than what God has commanded in their worship?  The answer is right here.  As in this case with ancient Israel, "they do what pleases them" and not what pleases God.
