'First Covenant' in the Bible

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

Now even the first covenant had regulations of divine worship and the earthly sanctuary.

For this reason He is the mediator of a new covenant, so that, since a death has taken place for the redemption of the transgressions that were committed under the first covenant, those who have been called may receive the promise of the eternal inheritance.

Therefore even the first covenant was not inaugurated without blood.
