And David sent messengers unto the men of Jabeshgilead
To return them thanks for their courage and boldness in rescuing the bodies of Saul and his sons out of the hands of the Philistines, and for their civility in the burial of them:
and said unto them, blessed [be] ye of the Lord;
which may be considered either as a wish, the Lord bless you for it, or as a prediction, the Lord will bless you:
that ye have showed this kindness unto your lord, [even] unto Saul,
and have buried him.
To bury the dead, with the Jews, was always reckoned an instance of humanity and kindness, and indeed of piety; an act done in imitation of God F26, who buried Moses, and so it might be expected the divine blessing would attend it.
