In the synagogue the Torah is read aloud in a fixed annual cycle of fifty-four weekly portions (parashiyot), one each Shabbat morning, with certain adjacent portions doubled in ordinary years so the sequence fits the calendar. Each portion is named for a distinctive word near its opening and is paired with a haftarah, a reading from the Prophets. The cycle closes and restarts on Simchat Torah. Vayeshev ('And he settled', Genesis 37:1-40:23) begins the Joseph narrative: his dreams and his brothers' envy, his sale into Egypt, the interlude of Judah and Tamar, his refusal of Potiphar's wife and imprisonment, and his interpretation of the dreams of Pharaoh's cupbearer and baker.
The interlude of Judah and Tamar (Genesis 38), interrupting the Joseph narrative at what seems a strange point, is read by rabbinic and later literary commentary as deliberately placed to develop Judah's own moral education in parallel with Joseph's, since Judah's eventual acknowledgement that 'she is more righteous than I' (Genesis 38:26) after wrongly withholding his son from her marks the same character who initiated selling Joseph into slavery beginning to develop the capacity for accountability that culminates, several portions later, in his plea to take Benjamin's place. Joseph's dreams of the sheaves and the sun, moon and eleven stars bowing to him (Genesis 37:5-11), told without evident tact to a family already resentful of his favoured status, are read by commentators including Rashi as narrated by the Torah in a manner that withholds judgement on whether Joseph's telling was wise, leaving readers to weigh his own contribution to his brothers' hostility alongside their disproportionate response.
