Of those ancestral bars enforceable in our time
Part 1What The Line Forbids, And At What Level
- The Torah's prohibition is on marriage. Marrying a non-Jew carries lashes by Scriptural law, and the Rambam applies the verse to every nation rather than the seven alone, citing the oath of the returnees in Ezra. The Tur limits the verse to its plain context. (12:1)
- Outside marriage the ban is Rabbinic. Relations without marriage draw stripes for rebellious conduct, a decree of the Sages made lest it lead to marriage. (12:2)
- Designation multiplies the liability. A man who designates a gentile woman for himself is liable under four separate Rabbinic headings at once and is struck for each; one who acts spontaneously is liable under one. (12:2)
- A priest's case is Scriptural. For a priest the prohibition of a zonah applies, so he incurs Scriptural lashes for the act itself with no marriage in question, since he cannot consecrate her at all. (12:3)
RememberThe Torah's line is drawn at marriage. Everything around it is the Sages' fence.
Part 2The Zealot, And Then Heaven
- Only in public, only in the act. The zealot who strikes is called praiseworthy where ten or more Jews are present and only while the transgression is underway; Pinchas and Zimri are both the proof and the limit. (12:4-5)
- A moment later and it is murder. Once the transgressor has withdrawn he may not be struck, even though he certainly sinned, and a zealot who kills him then is himself liable for execution. (12:5)
- No court will authorize it. A zealot who comes to the beit din for permission is not instructed to act, even during the transgression; and if the transgressor kills him in self defense he is not executed, because the zealot has the status of a pursuer. (12:5)
- Unpunished is not unanswered. Where neither zealot nor court acted, the Rambam brings Malachi: the penalty is karet, stated as the loss of descendants among the wise and the scholars. (12:6)
RememberPraised at Sinai, available only mid-act, never authorized, and lawfully resisted by force.
Part 3The Child, And The Space Between
- The child is the stated stake. A child of any other forbidden union is his father's son and a member of Israel, even a mamzer; a child of a gentile mother is not his son, which the Rambam calls a harm with no parallel. (12:7-8)
- A maidservant stands between categories. Immersed for servitude and bound by the servant's mitzvot, she has left the gentiles and not entered Israel, so her prohibition is Rabbinic, with stripes for rebellious conduct, no zealot, and no Scriptural lashes even for marrying her. (12:11, 12:14)
- Proof that it cannot be Scriptural. The Torah itself lets a master give his Hebrew servant a Canaanite maidservant, so no Scriptural prohibition can be involved; lashes attach only where she had been designated for a Jewish man. (12:11-12)
- Confused children are freed, not suspended. Where a Jewish child and a maidservant's child cannot be told apart, both are doubtful and the court compels the owner to free them both, so that neither is left unable to marry. (12:15)
RememberWhen the law cannot tell who is who, its instinct is to open the door.
Part 4Converts: Who May Marry In
- One law for the convert. A convert who accepts all the mitzvot, and a freed servant, are Jews in every respect and may marry into the community immediately, on the verse "there shall be one law." (12:17)
- Ammon and Moab: the men, forever. The bar is permanent but falls on the males only, which the Rambam gives as a halachah from Sinai; the Sages ground it in the Torah's stated reason, failing to meet Israel with bread and water, which did not concern the women. (12:18)
- Egypt and Edom: two generations. Male and female alike are barred in the first and second generations and permitted in the third, and where two of the four nations intermarry the offspring takes the heavier status. (12:19-21)
- Sannecherib dissolved all four. Because Assyria mixed the nations, any convert from any nation may marry in immediately today; the one permanent bar left is David's on the Netinim, for brazenness and cruelty, since Israel should be characterized by kindness and mercy. (12:22-25)
RememberEvery wall of ancestry in this chapter expired. The wall raised against cruelty did not.
