You shall not bow down to them or serve them, for I the LORD your God am a jealous God, visiting the iniquity of the fathers on the children to the third and the fourth generation of those who dishonour Me, but showing mercy to thousands, to those who love Me and keep My commandments. You shall not take the name of the LORD your God in vain, for the LORD will not leave anyone unpunished who takes His name in vain... (Exodus 20:5-6)
