In this Shabbat’s weekly Torah portion Beshalach Exodus 13:17 – 17:16, soon after allowing the children of Israel to depart from Egypt, Pharaoh chases after them to force their return, and the Israelites find themselves trapped between Pharaoh’s armies and the sea. G‑d tells Moses to raise his staff over the water; the sea splits to allow the Israelites to pass through, and then closes over the pursuing Egyptians. Moses and the children of Israel sing a song of praise and gratitude to G‑d.
In the desert the people suffer thirst and hunger, and repeatedly complain to Moses and Aaron. G‑d miraculously sweetens the bitter waters of Marah, and later has Moses bring forth water from a rock by striking it with his staff. He causes manna to rain down from the heavens before dawn each morning, and quails to appear in the Israelite camp each evening.
The children of Israel are instructed to gather a double portion of manna on Friday, as none will descend on Shabbat, the divinely decreed day of rest. Some disobey and go to gather manna on the seventh day, but find nothing. Aaron preserves a small quantity of manna in a jar, as a testimony for future generations.
In Rephidim, the people are attacked by the Amalekites, who are defeated by Moses’ prayers and an army raised by Joshua.
In the Haftara Prophets reading, Judges 4:4 – 5:31, describes the fall of the Canaanite general Sisera and his armies, who were swept away by the Kishon River, and Deborah’s ensuing song of thanks. This parallels this week’s Torah portion which discusses the drowning of the Egyptian forces in the Red Sea and the subsequent songs led by Moses and Miriam.
Deborah the Prophetess was the leader and judge of the Israelites at a difficult time; the Israelites were being persecuted by King Jabin of Canaan and his general Sisera. Deborah summoned Barak son of Abinoam and transmitted to him G‑d’s instruction: “Go and gather your men toward Mount Tabor, and take with you ten thousand men of the children of Naphtali and Zebulun. And I shall draw to you, to the brook Kishon, Sisera, the chieftain of Jabin’s army, with his chariots and his multitude; and I will give him into your hand.” At Barak’s request, Deborah accompanied him, and together they led the offensive.
Sisera was informed of the Israelites’ mobilization and he gathered his forces and proceeded towards the Kishon River. Barak’s army below and the heavens above waged battle against the Canaanites and utterly destroyed them. The river washed them all away; not one of the enemy survived.
The defeated general fled on foot and arrived at the tent of Jael, wife of Heber the Kenite. She invited him in and offered to hide him. When he fell asleep, Jael took a tent-peg and knocked it through Sisera’s temple.
The next chapter of the haftorah is the Song of Deborah, which describes the miraculous victory and thanks the One Above for His assistance.
