Amos 4:4-6

4"Come to Bethel, and transgress; to Gilgal, and multiply transgression; bring your sacrifices every morning, your tithes every three days;

5offer a sacrifice of thanksgiving of that which is leavened, and proclaim freewill offerings, publish them; for so you love to do, O people of Israel!" declares the Lord God.

6"I gave you cleanness of teeth in all your cities, and lack of bread in all your places, yet you did not return to me," declares the Lord.
