You shall have no other gods. Exodus 20:3.
We should fear, love and trust in God above all things.
Second Commandment: You shall not misuse the name of the Lord your God. Exodus 20:7.
We should fear and love God so that we do not curse, swear, use satanic arts, lie, or deceive by His name, but call upon it in every trouble, pray, praise and give thanks.
