Numbers 24:21

Cinite. From the top of the hill, he cast his eyes across the Dead Sea, and beholding the strong holds of the Cinite, whose country had been promised to the Hebrews, he is inspired to foretel what would happen to this people. He alludes to their name, which signifies a nest; (Calmet) and to the manner in which those nations of Arabia lived, in caverns cut out of a rock. (Bellon, ii. 61.)
