Charles Spurgeon Commentary Job 27:1-4

"And Job again took up his parable, and said, As God liveth, who hath taken away my right, And the Almighty, who hath vexed my soul: (For my life is yet whole in me, And the spirit of God is in my nostrils); Surely my lips shall not speak unrighteousness, Neither shall my tongue utter deceit." — Job 27:1-4 (ASV)

Moreover Job continued his parable, and said, As God liveth, who hath taken away my judgment; and the Almighty, who hath vexed my soul; all the while my breath is in me, and the spirit of God is in my nostrils, my lips shall not speak wickedness, nor my tongue utter deceit (Job 27:1–4).

He felt that it would be wicked for him to confess to what he had never done; it would be deceit for him to acknowledge crimes which he had never committed. Therefore, he most solemnly affirms, by the living God, that he never will permit the falsehood to pass his lips. He had not transgressed against God in the way his friends insinuated, and he would not admit that he had.
