1 Samuel 25:22

unto the enemies of David In the usual oath-formula the swearer invokes divine vengeance upon himself (1 Samuel 20:13), or upon the person adjured (1 Samuel 3:17). And so the Sept. here; "So God do to David." "The enemies of David" may possibly be an euphemism, introduced by a corrector who was unwilling to let David invoke vengeance upon himself for an oath which he afterwards broke. Comp. the note on 1 Samuel 20:16.

if I leave … any, &c. David vows that he will exterminate the family and not leave a single man alive. Cp. Deuteronomy 20:13.
