1 Samuel 31:2

The Philistines slew Jonathan, David's dear friend; God so ordering it for the further exercise of David's faith and patience; and that David might depend upon God alone for his crown, and receive it solely from him, and not from Jonathan; who doubtless, had he lived, would have speedily settled the crown upon David's head, which would have in some sort eclipsed the glory of God's grace and power in this work. There was also a special providence of God in taking away Jonathan, (who of all Saul's sons seems to have been the fairest for the crown,) for the preventing divisions, which have happened amongst the people concerning the successor; David's way to the crown being by this means made the more clear. Abinadab, called also Ishui, 1 Samuel 14:49. Ish-bosheth was not here, being possibly at home, for the management of public affairs there.
