Job 27:3

New English Translation

³for while^[a] my spirit^[b] is still in me,
and the breath from God is in my nostrils,

Job 27:3 tn The adverb עוֹד (ʿod) was originally a noun, and so here it could be rendered “all the existence of my spirit.” The word comes between the noun in construct and its actual genitive (see GKC 415 §128.e).
Job 27:3 tn The word נְשָׁמָה (n^eshamah) is the “breath” that was breathed into Adam in Gen 2:7. Its usage includes the animating breath, the spiritual understanding, and the functioning conscience—so the whole spirit of the person. The other word in this verse, רוּחַ (ruakh), may be translated as “wind,” “breath,” or “spirit/Spirit” depending on the context. Here, since it talks about the nostrils, it should be translated “breath.”

Job 27:4

New English Translation

⁴my^[a] lips will not speak wickedness,
and my tongue will whisper^[b] no deceit.

Job 27:4 tn The verse begins with אִם (ʾim), the formula used for the content of the oath (“God lives…if I do/do not…”). Thus, the content of the oath proper is here in v. 4.
Job 27:4 tn The verb means “to utter; to mumble; to meditate.” The implication is that he will not communicate deceitful things, no matter how quiet or subtle.
