Deuteronomy 5:7-9

7You must not have any other gods except me.

8You must not make any idol for yourself. Do not make a false god in the shape of anything that is in the sky above. Do not make one in the shape of anything on the earth or in the sea.

9You must not bend down your head to any idol or worship it. I am the Lord your God and I want you to belong to me alone. I will punish children because of the bad things that their fathers have done. I will also punish their grandchildren and their children too. That is how I will punish everyone who hates me.
