Amos 4:4-6

4“Go to Bethel and transgress; rebel even more at Gilgal! Bring your sacrifices every morning, your tithes every three days.15Offer leavened bread as a thank offering, and loudly proclaim your freewill offerings. For that is what you children of Israel love to do,” declares the Lord GOD.6“I afflicted all your cities with cleanness of teeth2 and all your towns with lack of bread, yet you did not return to Me,” declares the LORD.
