"The soul of Jonathan was knit with the soul of David, and Jonathan loved him as his own soul ... And
Jonathan stripped himself of the robe that was upon him, and gave it to David, and his garments ... and his girdle." 18:1-4
David and Jonathan "kissed one another, and wept with one another" when they parted for the last time. 20:41
"God hath delivered thine enemy into thine hand."
Did God deliver Saul into David's hand? Well, that's what Abishai thought, anyway. And God was involved in the whole thing, since he
laid a "deep sleep" upon them so that they wouldn't notice them sneak into Saul's tent (26.12). 26:8
