Deuteronomy 5:5-7

Authorized (King James) Version

⁵ (I stood between the Lord and you at that time, to shew you the word of the Lord: for ye were afraid by reason of the fire, and went not up into the mount;) saying, ⁶ I am the Lord thy God, which brought thee out of the land of Egypt, from the house of bondage.

⁷ Thou shalt have none other gods before me.
