Thou hast deceived, etc. . .The meaning of the prophet, is not to charge God with any untruth; but what he calls deceiving, was only the concealing from him, when he accepted of the prophetical commission, the greatness of the evils which the execution of that commission was to bring upon him.
20:8. For I am speaking now this long time, crying out against iniquity, and I often proclaim devastation: and the word of the Lord is made a reproach to me, and a derision all the day.
20:9. Then I said: I will not make mention of him, nor speak any more in his name: and there came in my heart as a burning fire, shut up in my bones, and I was wearied, not being able to bear it.
20:10. For I heard the reproaches of many, and terror on every side: Persecute him, and let us persecute him: from all the men that were my familiars, and continued at my side: if by any means he may be deceived, and we may prevail against him, and be revenged on him.
20:11. But the Lord is with me as a strong warrior: therefore they that persecute me shall fall, and shall be weak: they shall be greatly confounded, because they have not understood the everlasting reproach, which never shall be effaced.
20:12. And thou, O Lord of hosts, prover of the just, who seest the reins and the heart: let me see, I beseech thee, thy vengeance on them: for to thee I have laid open my cause.
Let me see, etc. . .This prayer proceeded not from hatred or ill will, but zeal of justice.
20:13. Sing ye to the Lord, praise the Lord: because he hath delivered the soul of the poor out of the hand of the wicked.
20:14. Cursed be the day wherein I was born: let not the day in which my mother bore me, be blessed.
Cursed be the day, etc. . .In these, and the following words of the prophet, there is a certain figure of speech to express with more energy the greatness of the evils to which his birth had exposed him.
