Yom Kippur Prayer Service

The Torah Portion, Vayikra (Leviticus) 16, describes the sacrifices offered on Yom Kippur in the time of the Temple. In this portion, God decrees that the tenth of Tishrei will always be a day of atonement.

Let it be a statute for you forever: in the seventh month, on the tenth of the month, you shall starve your vital energies and do no manner of work.... For on this day it shall bring atonement upon you, to purify you, before God shall you become pure of all your aberrations. (Vayikra (Leviticus) 16: 29-30)

Maftir is Bamidbar (Numbers) 29:7-11 which also describes the Yom Kippur day and sacrifice.

And on the tenth (day) of that seventh month there shall be for you a convocation to the Sanctuary, and you shall let your souls starve; you must do no manner of work. And you shall bring to God as an ascent offering to express compliance. (Bamidbar (Numbers) 29:7-8)

The Haftarah, Isaish 57:14-58:14, focuses on the purpose of fasting, to induce us to be more righteous in our relations with fellow men.

And you draw out your soul to the hungry, and an afflicted soul you sate, then your light shall shine in the darkness, and your darkness shall be like noon. (Isaiah 58:10)
