Jesus Himself called it the Law of Moses - so take it up with Him.
the oracles of God
This is he, that was in the church in the wilderness with the angel
which spake to him in [the mount Sina], and with our fathers:
who received the lively oracles [
to give unto us ] Acts 7:38
What advantage then hath the Jew? or what profit is there of circumcision?
Much every way:chiefly, because that unto them
were committed [the oracles of God]. Romans 3:2
For when for the time ye ought to be teachers, ye have need
that one teach you again which be the first principles of
[the oracles of God]; and are become such as have
need of milk, and not of strong meat. Hebrews 5:12
If any man speak, let him speak as [the oracles of God];
if any man minister, let him do it as of the ability which God giveth:
that God in all things may be glorified through Jesus Christ,
to whom be praise and dominion for ever and ever. Amen. 1 Peter 4:11
