Ki Teitzei

In the synagogue the Torah is read aloud in a fixed annual cycle of fifty-four weekly portions (parashiyot), one each Shabbat morning, with certain adjacent portions doubled in ordinary years so the sequence fits the calendar. Each portion is named for a distinctive word near its opening and is paired with a haftarah, a reading from the Prophets. The cycle closes and restarts on Simchat Torah. Ki Teitzei ('When You Go Out', Deuteronomy 21:10-25:19) contains more distinct commandments than any other parashah, on the captive woman, the wayward son, lost property, the wages of the poor, honest weights, divorce and marriage, and levirate duty, and closes with the charge to remember and blot out Amalek.

Ki Teitzei contains more individual commandments than any other weekly portion, seventy-four by the traditional count of the medieval Sefer HaChinuch (though Maimonides omits two, counting seventy-two), close to an eighth of the 613 commandments the rabbinic tradition finds in the whole Torah packed into a single reading. Its laws cluster overwhelmingly around the ordinary frictions of household and neighbour, lost property, a roof's safety fence, honest weights, a hired labourer's wages, rather than temple ritual, and the sheer density has made the portion a frequent starting point in later Jewish ethical and legal literature for organising commandments by social relationship rather than by cultic category.

Ki Teitzei's law of shiluach haken requires sending away a mother bird before taking eggs or chicks from her nest, promising long life for the observance (Deuteronomy 22:6-7), a command widely read, including by Maimonides in the Guide for the Perplexed, as teaching compassion toward animals and restraint from needless cruelty even in the pursuit of a permitted benefit. The Mishnah's tractate Berakhot records a strikingly different rabbinic position, that a prayer leader who explains the law as an expression of divine compassion should be silenced, reflecting a concern, discussed further in the Talmud, that this attributes God's motives with more confidence than is warranted rather than treating the law's deeper reason as unknown.

Source critics attribute Ki Teitzei's dense cluster of civil and family law to the Deuteronomic source, noting that its individual laws, unlike the more thematically organised collections in Leviticus and Numbers, appear to follow loose associative links from one topic to the next, a compositional style some scholars compare to other ancient legal collections arranged more by proximity of everyday concern than by abstract legal category. The provision sits within a broader Deuteronomic pattern of commandments that carry an explicit stated reward, here long life, a feature classical commentary contrasts with the majority of Torah law, which specifies no reward at all for its observance.
