Here, we're grappling with a seemingly specific scenario: a man with two wives, one loved and one "hated" – though "less favored" might be a kinder, more accurate translation. The Torah (Deuteronomy 21:15-17) commands that he can't favor the son of his beloved wife over the firstborn son of the less favored wife. Seems straightforward enough. But what are the boundaries of this law?

The text poses a question: are we only talking about unions that are forbidden by a simple negative commandment? You know, the "Thou shalt nots" of the Torah? What about relationships that carry the penalty of kareth (כָּרֵת)? Kareth is a severe spiritual penalty, often translated as "cutting-off," a premature death inflicted by Heaven. Surely, we might think, the rules of non-favoritism don’t apply in those severely prohibited relationships!

But that's where the repetition comes in. The text emphasizes the word "hated," stating "hated," "hated." According to Sifrei Devarim, this repetition broadens the scope. It tells us, no, even in unions that carry the heavy consequence of kareth, this principle of fairness still applies! Even when a relationship is deeply problematic, the offspring still have rights. It’s a powerful statement about inherent dignity and the reach of ethical obligations.

Okay, so we've expanded the scope. But could we expand it too far?

The text raises another possibility: what about a maidservant or a Canaanite woman? Would the rules of non-favoritism apply there as well?

Here, the text becomes very precise. It quotes the verse: "If there be to a man… and they bear to him sons." The key phrase is "they bear to him sons." Sifrei Devarim emphasizes that where there is "being" (יֵשׁ), meaning where the sons are legally and halachically his, then this law of non-favoritism absolutely applies. But in the case of a maidservant or a Canaanite woman, the sons are not automatically considered his. Halachically, their status is different. The children follow the status of the mother. Thus, the halachah of non-favoritism doesn’t apply in these cases.

What’s truly remarkable is how this passage uses textual interpretation to navigate complex ethical terrain. It's not just about following rules; it’s about understanding the principles behind them. It's about grappling with the nuances of relationships, legal definitions, and moral obligations.

This passage in Sifrei Devarim invites us to consider: How far does our responsibility extend? Where do we draw the line between what is permissible and what is ethical? And how do we balance the letter of the law with the spirit of fairness and compassion? It’s a conversation that continues to resonate today, reminding us that justice and ethics are not always simple, but they are always worth striving for.
