Deuteronomy 17:1-3

New International Version - UK

17 Do not sacrifice to the Lord your God an ox or a sheep that has any defect or flaw in it, for that would be detestable to him.

² If a man or woman living among you in one of the towns the Lord gives you is found doing evil in the eyes of the Lord your God in violation of his covenant, ³ and contrary to my command has worshipped other gods, bowing down to them or to the sun or the moon or the stars in the sky,
