Thursday Chukas

The Jews arrive at Mount Hor. At G‑d's command, Moses, Aaron and Aaron's son, Elazar, go up the mountain. Aaron removes his high priest's vestments and Elazar dons them. Aaron then passes away. The entire nation mourns Aaron's death for thirty days. The Amalekites, disguised as Canaanites, attack the Jews. The Jews pray to G‑d and are victorious in battle. The Jews complain about their food, claiming that they are "disgusted" by the manna. G‑d dispatches serpents into the Israelite encampment, and many Jews die. Moses prays to G‑d on the Jews' behalf. Following G‑d's instructions, Moses fashions a copper serpent and places it atop a pole. The bitten Jews would look at this snake and be healed.
