Vayigash or Vaigash (וַיִּגַּשׁ—Hebrew for "and he drew near" or "then he drew near," the first word of the parashah) is the eleventh weekly Torah portion (פָּרָשָׁה, parashah) in the annual Jewish cycle of Torah reading. It constitutes Genesis 44:18–47:27. In the parashah, Judah pleads on behalf of his brother Benjamin, Joseph reveals himself to his brothers, Jacob comes down to Egypt, and Joseph's administration of Egypt saves lives but transforms all the Egyptians into bondmen.
