The Torah's rule against cross-dressing in (Deuteronomy 22:5) is brief and absolute. Targum Jonathan rewrites it entirely, replacing the general prohibition with something specific and startling: "Neither fringed robes nor tephillin which are the ornaments of a man shall be upon a woman." The Targum names the exact ritual items—fringed garments (tzitzit) and tefillin (phylacteries)—that women must not wear. And it adds the reverse: "neither shall a man shave himself so as to appear like a woman." The Hebrew says none of this.
The bird's nest commandment gets an afterlife attached. Send the mother bird away and take the young, says the Torah. The Targum adds the reward: "that it may be well with thee in this world, and that thou mayest prolong thy days in the world to come." A simple act of animal compassion becomes a ticket to eternal life.
The laws about the slandered bride are expanded with legal terminology. The father and mother "may have licence from the court of judgment to produce the linen with the witnesses of her virginity." The Targum specifies the venue—"at the door of the beth din," the rabbinic court. The penalty of one hundred shekels is named, and the phrase "upright virgin of Israel" replaces the Torah's simpler language.
The adultery laws receive a chilling addition. When a man is found with another's wife, "both of them shall be put to death"—but the Targum specifies the method: "strangulation with the napkin." And then adds: "Even if she be with child, they shall not wait till she is delivered, but in the same hour they shall put them to death." The Torah does not address pregnancy in this context. The Targum does, with unflinching severity. The mixed fabrics prohibition gets technical detail too—the banned garment is "combed or netted, or interwoven with woollen and linen mixed together."
