"Yerahme'el son of the king "

Yerahmeel is identified in Jer. 36:26 as one of the trio sent by Jehoiakim to arrest Jeremiah. The existence of the Baruch son of Neriah bulla in the same collection makes it virtually certain that this seal belongs to the person identified in Jer. 36.

Jer. 36:26 "And the king commanded Jerahmeel the king's son, Seraiah the son of Azriel, and Shelemiah the son of Abdeel to seize Baruch the scribe and Jeremiah the prophet, but the LORD hid them."

Scholars debate the meaning of the phrase "son of the king." Some arguing it refers to a prince (direct descendant), others to a member of the extended royal family. It is notable that the Hebrew Bible designates five people as a "son of the king ," only one of which is otherwise identified as a member of the royal family, viz., Jotham, son of Uzziah. (2 Kgs 15) Three of the remaining referents are identified with "official" activities including arresting prophets. (In addition to Yerahme'el, Joash is involved in arresting a prophet (1 Kgs 22:26), Ma'aseiah is somehow connected with royal officials (Jer 35:4)
