'First Covenant' in the Bible

And I will remember [the] first covenant for them--whom I brought out from the land of Egypt {in the sight of} the nations {to be their God}. I [am] Yahweh.'"

And because of this, he is the mediator of a new covenant, in order that, [because] a death has taken place for the redemption of transgressions [committed] during the first covenant, those who are the called may receive the promise of the eternal inheritance.
