Job 2:9

Then said his wife to him,.... The Jews , who affect to know everything, say, that Job's wife was Dinah, the daughter of Jacob, as the Targum, but this is not very likely; however, we may observe that polygamy had not obtained in these early times; Job had but one wife, and very probably she is the same that after all this bore him ten children more; since we never read of her death, nor of his having any other wife, and might be a good woman for anything that appears to the contrary; and Job himself seems to intimate the same, though she was in the dark about this providence, and under a sore temptation on that account; and therefore says to her husband,dost thou still retain thine integrity?
