'First Covenant' in the Bible

If the first covenant had been faultless, there would have been no need to look for a second one,

Now even the first covenant had regulations for worship and an earthly sanctuary.

This is why the Messiah is the mediator of a new covenant; so that those who are called may receive the eternal inheritance promised them, since a death has occurred that redeems them from the offenses committed under the first covenant.

This is why even the first covenant was not put into effect without blood.
