'First Covenant' in the Bible

For if that first Covenant had been free from imperfection, there would have been no attempt to introduce another.

Now even the first Covenant had regulations for divine worship, and had also its sanctuary--a sanctuary belonging to this world.

And because of this He is the negotiator of a new Covenant, in order that, since a life has been given in atonement for the offences committed under the first Covenant, those who have been called may receive the eternal inheritance which has been promised to them.

Accordingly we find that the first Covenant was not inaugurated without blood.
