yi.shay is the personal name of David’s father, named in family records, narratives, and later lineage language.

The name identifies the father of David: Samuel is sent to him and examines his sons in 1 Samuel 16:1, David is repeatedly called his son in accounts involving Saul, and genealogical notices place him between Obed and David in Ruth 4:22. Later passages retain the name in references to David’s ancestry, including the “stock” and “root” imagery in Isaiah 11:1 and Isaiah 11:10.

   The proper noun identifies the man whose sons are brought before Samuel in 1 Samuel 16:10 and whose youngest son is sent for in 1 Samuel 16:11. In Ruth 4:22 the APB renders the genealogy “Obed begot Jesse, and Jesse begot David,” while Isaiah 11:1 uses his name in the clause about a shoot from his stock.

In the Anselm Project Bible: The APB normally presents the name as “Jesse,” often in family phrases such as “son of Jesse” and “Jesse begot David.” In Isaiah 11:1 and Isaiah 11:10 it retains the name within lineage imagery; these English phrasings are readings of the whole translated clauses, not definitions.
