   The plural noun is used of vessels coming from Kittim in Numbers 24:24 and Daniel 11:30, and of messengers going out in vessels in Ezekiel 30:9. The singular noun occurs in Isaiah 33:21 in the clause that no great vessel will pass through the rivers and streams; in Isaiah 33:21 the APB renders the clause "no fleet with oar will go in it, and no great ship will pass through it."

In the Anselm Project Bible: The APB presents the plural forms as "Ships" in Numbers 24:24 and Daniel 11:30 and as "ships" in Ezekiel 30:9; in Isaiah 33:21 it uses both "fleet with oar" and "great ship" within the verse. These English expressions confirm the verse contexts rather than separately define the term.
