'First Covenant' in the Bible

If that first Covenant had been faultless, there would have been no occasion for a second.

It is true that even the first Covenant had its regulations for divine worship, and its Sanctuary--though only a material one.

And that is why he is the intermediary of a new Covenant; in order that, as a death has taken place to effect a deliverance from the offenses committed under the first Covenant, those who have received the Call may obtain the eternal inheritance promised to them.

This explains why even the first Covenant was not ratified without the shedding of blood.
