Deuteronomy - Chapter 5

In this chapter Moses says:

“The Lord our God made a covenant with us at Mount Sinai. The Lord did not make this covenant with our ancestors, but with all of us who are alive today. At the mountain the Lord spoke to you face to face from the heart of the fire. I stood as an intermediary between you and the Lord, for you were afraid of the fire and did not want to approach the mountain. He spoke to me, and I passed his words on to you. This is what he said:"

and then Moses repeats the 10 Commandments.

These 10 Commandments are quoted by Jesus in his Sermon on the Mount (in Matthew 5), when he refers to the Commandments and then amplifies them.
