'Merchant ships' in the Bible

Along with Hiram's fleet, the king had a fleet of large merchant ships that sailed the sea. Once every three years the fleet came into port with cargoes of gold, silver, ivory, apes, and peacocks.

Jehoshaphat built a fleet of large merchant ships to travel to Ophir for gold, but they never made the voyage because they were shipwrecked in Ezion Geber.
