Parashah Chukkat from Numbers 19:1–22:1 sets out the laws of corpse contamination (tumat hamet) and purification with the water of lustration prepared with the Red Cow (פָרָה אֲדֻמָּה‎, parah adumah, also called the “Red Heifer”), and reports the deaths of Miriam and Aaron, the failure of Moses at the Waters of Meribah, and the conquest of Arad, the Amorites, and Bashan.
