2 Samuel 1:16-20

And David said to him, “Your blood is on your head, because your own mouth has testified against you, saying, ‘I have finished off the Lord’s anointed.’ ” David’s Song of Mourning for Saul and Jonathan

Then David sang this song of mourning over Saul and his son Jonathan,

and he told them to teach the sons of Judah the mourning song of the bow; behold, it is written in the Book of Jashar.

“Your beauty, Israel, is slaughtered on your high places! How the mighty have fallen!

“Tell it not in Gath, Proclaim it not in the streets of Ashkelon, Or the daughters of the Philistines will rejoice, The daughters of the uncircumcised will celebrate.
