'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.'"

For if that first covenant had been faultless, then would no place have been sought for a second.

Now even a first covenant had ordinances of divine service, and its sanctuary, a sanctuary of this world.

And for this cause he is the mediator of a new covenant, that a death having taken place for the redemption of the transgressions that were under the first covenant, they that have been called may receive the promise of the eternal inheritance.

Wherefore even the first covenant hath not been dedicated without blood.
