Job 42:14 - Joseph Benson’s Commentary on the Old and New Testaments

And he called the name of the first, Jemima Which the LXX., and Vulgate, as derived from יום, jom, interpret day. The Targum is, Her beauty was like that of the day. The name of the second, Kezia Because she was precious like cassia, says the Targum. The meaning probably is, Pleasant as cassia, or fine spices. And the name of the third, Keren- happuch Which the LXX. render, Αμαλθαιας κερας, Amalthea's horn, or, The horn of plenty. The Targum, however, says she was so called, because the brightness of her face was like that of an emerald. Hence some interpret the name, The horn, or child, of beauty.
