For finding fault with them,.... Both with the covenant, which had its faults, and with the people who continued not in it, and were therefore disregarded by the Lord, Heb 8:9he saith, behold, the days come (saith the Lord) when I will make a new covenant with the house of Israel, and with the house of Judah; the words are cited from Jer 31:31 in which God promises a "new covenant"; so called, not because newly made; for with respect to its original constitution, it was made from eternity; Christ the Mediator of it, and with whom it was made, was set up from everlasting; and promises and blessings of grace were put into his hands before the world began: nor is it newly revealed, for it was made known to Adam, and in some measure to all the Old Testament saints, though it is more clearly revealed than it was; but it is so called in distinction from the former administration of it, which is waxen old, and vanished away; and with respect to the order of succession, it taking place upon the former being removed; and on account of the time of its more clear revelation and establishment being in the last days; and because of its mode of administration, which is different from the former, in a new way, and by the use of new ordinances; and because it is always new, its vigour and efficacy are perpetual; it will never be antiquated, or give place to another; and it provides for, and promises new things, a new heart, a new spirit, &c.
to which may be added, that it is a famous, excellent covenant, there is none like it; just as an excellent song is called a new song.
