'Caravans' in the Bible

"In the days of Shamgar, son of Anath, in the days of Ja'el, caravans ceased and travelers kept to the byways.

The caravans of Tema looked, the companies of Sheba counted on them:

The burden against Arabia. In the forest of Arabia shall ye lodge, ye caravans of Dedanites.

The ships of Tarshish were thy caravans for thy traffic; and thou wast replenished, and highly honoured, in the heart of the seas.
