I have written to him the great things of my law,.... Which was given by Moses to Israel at the appointment of God, in which were many commands, holy, just, and true; a multiplicity of them, as the Targum, relating to the honour of God, and the good of men; many excellent and useful ones of a moral nature, and others of a ceremonial kind; and particularly concerning sacrifices, showing what they should be, the nature and use of them, and where and on what altar they should be offered; and which pointed at the great sacrifice of the Messiah, who is both altar, sacrifice, and priest: and these things were frequently inculcated by the prophets, who from time to time were sent unto them; so that the Lord was continually writing these things to them by them, as Jarchi, Kimchi, and Ben Melech interpret it; hence they could not plead ignorance, and excuse themselves on that account.
The law sometimes not only designs the law of the decalogue, and the ceremonial law, respecting sacrifices, &c.
