Expanded Bible

³ But David ·took an oath [vowed; swore], saying, “Your father knows very well that ·you like me [^LI have found favor in your sight]. He says to himself, ‘Jonathan must not know about it, or he will be ·upset [hurt; grieved].’ As surely as the Lord lives and as you live, I am only a step away from death!”
