Parshiyot Hukkat-Balak – 5786

June 25, 2026

Rabbi Wendy Love Anderson

A D’var Torah for Parshiyot Hukkat-Balak By Rabbi Wendy Love Anderson (2023) The Strangest Mitzvah What do you think is the strangest commandment in the entire Torah? There’s some pretty stiff competition. Is it the prohibition on combining wool and linen? The insistence that it’s fine to eat cows and goats but not pigs? The sandal and spitting ritual that accompanies a brother’s refusal to marry his widowed sister-in-law? The prohibition against rounding the corners of one’s beard? While some commandments are morally challenging, others are intellectually puzzling, making them difficult to explain, much less defend against criticism. Parashat Hukkat opens with a novel Israelite ritual: in order to prepare a special liquid that will be used to ritually purify individuals contaminated by contact with a human corpse, an unblemished red heifer must be slaughtered outside the camp and (after some priestly blood-sprinkling) completely burnt, together with cedar, hyssop, and crimson dye. Although this ritual was...

Parshiyot Hukkat-Balak 5783

Who knew! What a wonder! The joy, uplift, delight, and hope that awareness of these mostly unseen birds bring me is deep and unbounded. They make my day. Balak, King of Moab, sends Bilam to curse the Israelites. Along the way, Bilam has a...

Parashat Hukkat – Balak 5780

July 2, 2020

A D’var Torah for Parashat Hukkat – Balak By Rabbi Len Levin We are reading two parshiyot this week, each rich in lessons. We can only present a few hors d’oeuvres here; enjoy the rest at your leisure! * * * The ritual of the red heifer raised many puzzles for the rabbis, to the point that they said that the wise king Solomon, frustrated in trying to solve them, gave up in despair and said: “All this I tested with wisdom, I thought I could fathom it, but it eludes me.” (Ecclesiastes 7:23; Pesikta Rabbati 14:1) The central mystery arises from the fact that it is a ritual for purification from contact with death. We are still struggling to understand the causes of death, which even now are evolving and mutating as we try to cope with them. A favorite question was: How is it that the ashes of the heifer...
