The Objective of Atonement The objective of the Atonement celebrated every year as "Yom Kippur" was a prophecy to point to the day when HaShem rejected Israel, the Ten Tribes and confirmed Judah to remain as one kingdom before the Lord forever. That's in Psalm 78:67-69. Both kingdoms, Israel and Judah had rejected God's Covenant with His People but, God had promised David that Judah would remain as a lamp in Jerusalem for his sake. (I Kings 11:36) Therefore, Israel had to atone for Judah. Since then, Yom Kippur is still observed but in memory; no longer as a prophecy.
