Exodus 20:3-7

No other gods, only me. No carved gods of any size, shape, or form of anything whatever, whether of things that fly or walk or swim. Don’t bow down to them and don’t serve them because I am GOD, your God, and I’m a most jealous God, punishing the children for any sins their parents pass on to them to the third, and yes, even to the fourth generation of those who hate me. But I’m unswervingly loyal to the thousands who love me and keep my commandments. No using the name of GOD, your God, in curses or silly banter; GOD won’t put up with the irreverent use of his name.
