ya.shen denotes sleeping, and in a smaller group of contexts becoming old or long-standing.

The predominant use describes persons sleeping, whether lying down, dreaming, remaining unawakened, or sleeping securely; it can also describe an enduring sleep marked by not waking. A smaller Niphal cluster concerns growing old or being old, including a chronic condition and stored old provisions.

1. Sleeping or remaining asleep · dominant

   Qal verbal forms describe sleeping as an action: in Genesis 2:21 the man sleeps after a deep sleep falls on him, and in Genesis 41:5 he sleeps and dreams again. The same use includes sleep that is not interrupted: in 1 Samuel 26:12 no one awakes because deep sleep has fallen on them, while Jeremiah 51:39 describes sleep followed by not waking.

2. Growing old or being old · occasional

   Niphal forms mark an old or long-standing condition. In Deuteronomy 4:25 the APB renders the clause "grow old in the land"; in Leviticus 13:11 it calls the condition "chronic leprosy," and in Leviticus 26:10 it refers to "the old that has been stored."

In the Anselm Project Bible: The APB commonly presents the sleep use with "slept," "sleep," or "deep sleep," including clauses about not waking. In the Niphal contexts it instead uses "grow old," "chronic," and "old"; these are translation renderings of whole clauses.
