camel: the large humped desert animal used for riding, carrying loads, and as a measure of wealth
This is the ordinary word for the camel, the tall humped animal that could cross stretches of desert other livestock could not. In the Bible the camel is above all a beast of burden and long-distance travel: it carries people, goods, and the gifts and dowries that move between families and nations.
Because a herd of camels represented serious wealth, the word often appears in lists that size up how rich a person or a raiding tribe was, right alongside sheep, cattle, and donkeys. It is also the animal of the caravan and the nomad, so it turns up wherever traders, Midianites, or desert raiders are on the move.
The meaning is steady throughout: every occurrence points to the same animal. The variety is in the setting, not in the sense, which is why a single plain definition covers the whole range.
