Beshalach, Beshallach, or Beshalah (בְּשַׁלַּח – Hebrew for "when [he] let go," the second word and first distinctive word in the parashah) is the sixteenth weekly Torah portion (פָּרָשָׁה, parashah) in the annual Jewish cycle of Torah reading and the fourth in the Book of Exodus. It constitutes Exodus 13:17–17:16. In this parashah, Pharaoh changes his mind and sends his army after the Jewish people, trapping them at the Sea of Reeds. God commands Moses to split the sea, allowing them to pass, then closes the sea back upon the Egyptian army. It also contains the miracles of manna and clean water.
The parashah is made up of 6,423 Hebrew letters, 1,681 Hebrew words, and 116 verses, and can occupy about 216 lines in a Torah Scroll (סֵפֶר תּוֹרָה, Sefer Torah).
Jews read it the sixteenth Sabbath after Simchat Torah, in January or February. As the parashah describes God's deliverance of the Israelites from Egypt, Jews also read part of the parashah, Exodus 13:17–15:26, as the initial Torah reading for the seventh day of Passover. And Jews also read the part of the parashah about Amalek, Exodus 17:8–16, on Purim, which commemorates the story of Esther and the Jewish people's victory over Haman's plan to kill the Jews, told in the book of Esther.Esther 3:1 identifies Haman as an Agagite, and thus a descendant of Amalek. Numbers 24:7 identifies the Agagites with the Amalekites. A Midrash tells that between King Agag's capture by Saul and his killing by Samuel, Agag fathered a child, from whom Haman in turn descended.
