a. "anyone who has set aside the law of moses dies without mercy"
pulled from a few verses in the OT;
numbers 15:28-31
28. `The priest shall make atonement before the LORD for the person who goes astray when he sins unintentionally,
making atonement for him that he may be forgiven.
29. `You shall have one law for him who does anything unintentionally, for him who is native among the sons of Israel
and for the alien who sojourns among them.
30. `But the person who does anything defiantly, whether he is native or an alien, that one is blaspheming
the LORD; and that person shall be cut off from among his people.
31. `Because he has despised the word of the LORD and has broken His commandment, that person shall be
completely cut off; his guilt will be on him.' "
deut 17:2-7
2. "If there is found in your midst, in any of your towns, which the LORD your God is giving you, a
man or a woman who does what is evil in the sight of the LORD your God, by transgressing His covenant,
3. and has gone and served other gods and worshiped them, or the sun or the moon or any of the heavenly
host, which I have not commanded,
4. and if it is told you and you have heard of it, then you shall inquire thoroughly. Behold, if it is
true and the thing certain that this detestable thing has been done in Israel,
5. then you shall bring out that man or that woman who has done this evil deed to your gates, that is,
the man or the woman, and you shall stone them to death.
6. "On the evidence of two witnesses or three witnesses, he who is to die shall be put to death; he shall
not be put to death on the evidence of one witness.
7. "The hand of the witnesses shall be first against him to put him to death, and afterward the hand of all
the people. So you shall purge the evil from your midst.
deut 13:8 tosses in the 'without pity' phrase.
b. judgement in the OT: death and fire; judgement in the NT: fire.
let's acknowledge that this is rough; you get killed for turning away from god?
yup.
to be honest though, that's the least of your problems in that case; we've introduce the idea of spiritual judgement
at this point.
in the old testament, the idea of keeping god's people on god's side was critical. the judgement here was important to that
end, but was less than god's ultimate judgement.
in the new testament, we are not a nation per se; but the real judgement is still in place, and that's what the author wants to
remind us of.
it's worse in the NT because it goes against greater revelation however.
