Biblical and extrabiblical evidence suggests that of the Arabian tribes, the Qedarites were most prominent in their contacts with the world outside of the Arabian Peninsula. Like other nomadic groups, they lived primarily in unfortified encampments. Pastoralists and traders in livestock, such as male lambs, rams and goats, they also played a key role in the prosperity of Gaza's incense trade, controlling traffic in the desert regions between Egypt and Palestine. As a result of their trading activities, there were clans from among the Qedarites that became wealthy.
