This is was the situation back when the Real Yeshua was preaching and teaching in Galilee and Judea. The Sadducees taught that after death everyone went to Sheol. Job gives us a glimpse of the way the ancient Hebrews viewed Sheol – the abode of the dead -- in Job 10:20-22.
Are not my days few? Cease then, and let me alone, that I may take comfort a little before I go whence I shall not return, even to the land of darkness and the shadow of death; a land of darkness, as darkness itself; and of the shadow of death, without any order, and where the light is as darkness.
The author of Psalm 115 (verses 16-17) shared Job’s view -- or Job shared his view -- of Sheol.
