'First Covenant' in the Bible

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

Then verily the first covenant had also ordinances of divine service, and an earthly sanctuary.

And for this cause he is the mediator of the new covenant, that by means of death, for the redemption of the transgressions that were under the first covenant, they who are called might receive the promise of eternal inheritance.

Hence neither the first covenant was dedicated without blood.
