'Mediator' in the Bible

Why, then, was the Law added? Because of transgressions, until the descendant came about whom the promise pertained. It was put into effect through angels by means of a mediator.

Now a mediator involves more than one party, but God is one.

There is one God. There is also one mediator between God and human beings a human, the Messiah Jesus.

This is why the Messiah is the mediator of a new covenant; so that those who are called may receive the eternal inheritance promised them, since a death has occurred that redeems them from the offenses committed under the first covenant.

to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better message than Abel's.
