1 Samuel 25:26

25:26 “Now, my lord, as surely as the Lord lives and as surely as you live, it is the Lord who has kept you from shedding blood and taking matters into your own hands. Now may your enemies and those who seek to harm my lord be like Nabal.

Job 27:2

27:2 “As surely as God lives, ¹  who has denied me justice, ² 

the Almighty, who has made my life bitter ³  –

[27:2]  ¹ tn The expression חַי־אֵל (khay-’el) is the oath formula: “as God lives.” In other words, the speaker is staking God’s life on the credibility of the words. It is like saying, “As truly as God is alive.”

[27:2]  ² tn “My judgment” would here, as before, be “my right.” God has taken this away by afflicting Job unjustly (A. B. Davidson, Job, 187).

[27:2]  ³ tn The verb הֵמַר (hemar) is the Hiphil perfect from מָרַר (marar, “to be bitter”) and hence, “to make bitter.” The object of the verb is “my soul,” which is better translated as “me” or “my life.”
