JOAB was commander-in-chief of David's army. He signaled the beginning and ending of battle by blowing a trumpet (II Kings 2:28, 18:16, 20:22).
At Januarie's wedding feast, every course is preceded by the kind of trumpeting that neither Joab nor Theodamas had ever heard, MerchT 1718-1721. The dreamer sees Joab in the great hall where many musicians have gathered in company with other trumpeters, Misenus and Theodamas, HF III.1245. [Messenus: Theodamas]
The name appears medially, MerchT 1719; HF III.1245.
