Exodus 20:2-6 (ESV)

2 “I am the Lord your God, who brought you out of the land of Egypt, out of the house of slavery.

3 “You shall have no other gods before me.

4 “You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth. 5 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 hate me, 6 but showing steadfast love to thousands of those who love me and keep my commandments.

2 Corinthians 11:2-4

2 For I feel a divine jealousy for you, since I betrothed you to one husband, to present you as a pure virgin to Christ. 3 But I am afraid that as the serpent deceived Eve by his cunning, your thoughts will be led astray from a sincere and pure devotion to Christ. 4 For if someone comes and proclaims another Jesus than the one we proclaimed, or if you receive a different spirit from the one you received, or if you accept a different gospel from the one you accepted, you put up with it readily enough.
