Ki Tisa

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. Ki Tisa ('When you take', Exodus 30:11-34:35) moves from the half-shekel census and the appointment of the craftsmen to the crisis of the golden calf, Moses' shattering of the tablets and his intercession, and the revelation of the thirteen attributes of divine mercy and the second set of tablets.

The golden calf's construction, initiated while Moses remained on the mountain receiving the very laws against idolatry the people were about to violate, is read by rabbinic commentary as compounded by timing, the sin occurring on what the people miscounted as the fortieth day of Moses' absence, a miscalculation later linked in tradition to the fast of the seventeenth of Tammuz, when Moses is said to have descended and shattered the tablets upon witnessing the scene (Exodus 32:19). Moses' intercession, offering to have his own name blotted from God's book rather than see the people destroyed (Exodus 32:32), is read across the commentary tradition as among the most radical instances of vicarious pleading in the Hebrew Bible. The second set of tablets, carved by Moses himself rather than given ready-made as the first had been (Exodus 34:1), is read by commentators as marking a shift toward human partnership in the covenant's physical renewal, following the community's own failure that had shattered its first, wholly divine, form.

Ki Tisa holds one of the Torah's gravest episodes, the golden calf, and one of its most consoling, the revelation of the thirteen attributes of mercy (Exodus 34:6-7), which became a central prayer of the penitential seasons and the Day of Atonement. The narrative of sin, shattered tablets, intercession and renewed covenant supplied Judaism with its enduring theology of repentance and divine forgiveness.

The thirteen attributes of mercy, recited to Moses as God passes before him, merciful and gracious, slow to anger, abundant in kindness and truth (Exodus 34:6-7), became, in the form fixed by later liturgy, the central refrain of the penitential prayers recited through the month before Rosh Hashanah and on fast days, and the Talmud records a tradition that God instructed Moses in the very wording Israel should use when pleading for forgiveness. Rabbinic commentary reads the sequence, sin, punishment, intercession, renewed revelation, as establishing the Torah's enduring pattern for how covenant survives rupture, a pattern later Jewish liturgy for Yom Kippur draws on directly. Moses' request to see God's glory, answered only by being shown God's 'back' after being hidden in a cleft of rock while the divine presence passes (Exodus 33:18-23), is read by Jewish philosophical commentary, particularly Maimonides, as a statement about the limits of human comprehension of the divine essence, only its effects, not its nature, being accessible even to Moses.
