Ahijah the prophet, whose home was in Shiloh, is so designated (1 Kings 11:29; 15:29). The plural form occurs (1 Chr. 9:5), denoting the descendants of Shelah, Judah’s youngest son.
Shilonite
Ahijah the Shilonite appears only briefly, yet the books of Kings keep coming back to his word. This prophet finds Jeroboam alone in a field, when Jeroboam has “clad himself with a new garment” (1 Kings 11:29). Later, when the king turns a deaf ear to the people, the writer says “the cause was from the LORD, that he might perform his saying” (1 Kings 12:15). The end of Jeroboam’s house is again traced to what the LORD spoke “by his servant Ahijah the Shilonite.” Chronicles even lists his prophecy among the records of Solomon’s reign. Start with 1 Kings 11:29.
