So great a contrast there is between the last verse of the preceding paragraph and the beginning of this, that I cannot but suppose the Prophet is not speaking these things of himself. And I the rather am inclined to suppose this from the great sameness that there is in the words here spoken, to what we meet with in Job's complaint: so as that one might conclude the Prophet quoted them from Job. See Job 3:3, etc. The Reader will remember, that I do not decide upon it, I refer him to the passage. But if the Prophet, like the Patriarch, uttered this vehement lamentation, we only learn from both, what a compound of grace and corruption there is in the best of men as men: It is thou only blessed Jesus, of whom it can be said, there was no guile found in thy lips; but as a lamb before her shearers is dumb, so thou openedst not thy mouth. 1 Peter 2:22-23.

14 Cursed be the day wherein I was born: let not the day wherein my mother bare me be blessed.
15 Cursed be the man who brought tidings to my father, saying, A man child is born unto thee; making him very glad.
16 And let that man be as the cities which the LORD overthrew, and repented not: and let him hear the cry in the morning, and the shouting at noontide;
17 Because he slew me not from the womb; or that my mother might have been my grave, and her womb to be always great with me.
18 Wherefore came I forth out of the womb to see labour and sorrow, that my days should be consumed with shame?
