Jewish law and custom prescribe ritual hand washing in a number of situations. This practice is generally known by the Hebrew term netilath yadayim (Hebrew: נטילת ידיים, romanized: Nəṭilat̲ yād̲āyim), which means "taking up of the hands."

The Talmud used the requirement of handwashing in Leviticus 15:11, "The person who is touched by one who has a discharge without rinsing his hands in water must wash their clothes and bathe with water, and they will be unclean till evening," as a hint for general handwashing law, using the principle of asmakhta or "allusion."
