The New Covenant in the Gospels

Christians are sometimes surprised to discover that the term "new covenant" only appears once in the gospel accounts, though all four focus on the person and work of Jesus of Nazareth. In fact, the word "covenant" is virtually absent from these texts. Outside of the Upper Room accounts in the synoptic gospels, it occurs only once in Luke's gospel, and then in reference to the Abrahamic Covenant. However, the concept of the new covenant is woven into the fabric of the four gospel accounts, but as it is understood in terms of God's interactions with and promises to His covenant people as recorded in the Old Testament scriptures.
