2 Samuel 1:17 (KJV)

And they mourned, and wept, and fasted until even, for Saul, and for Jonathan his son, and for the people of the LORD, and for the house of Israel; because they were fallen by the sword.

And David said unto the young man that told him, Whence art thou? And he answered, I am the son of a stranger, an Amalekite.

And David said unto him, How wast thou not afraid to stretch forth thine hand to destroy the LORD's anointed?

And David called one of the young men, and said, Go near, and fall upon him. And he smote him that he died.

And David said unto him, Thy blood be upon thy head; for thy mouth hath testified against thee, saying, I have slain the LORD's anointed.

(Also he bade them teach the children of Judah the use of the bow: behold, it is written in the book of Jasher.)

The beauty of Israel is slain upon thy high places: how are the mighty fallen!

Tell it not in Gath, publish it not in the streets of Askelon; lest the daughters of the Philistines rejoice, lest the daughters of the uncircumcised triumph.

Ye mountains of Gilboa, let there be no dew, neither let there be rain, upon you, nor fields of offerings: for there the shield of the mighty is vilely cast away, the shield of Saul, as though he had not been anointed with oil.

From the blood of the slain, from the fat of the mighty, the bow of Jonathan turned not back, and the sword of Saul returned not empty.
