Therefore David took hold of his own clothes and tore them, and so did all the men who were with him. And they mourned and wept and fasted until evening for Saul and for Jonathan his son, for the people of the LORD and for the house of Israel, because they had fallen by the sword.
2 Samuel 1:11-12

Saul had jealously pursued David, seeking to kill him for nearly ten years.

Twice during that time David had opportunity to kill Saul, but refused to take the life of the man God ordained to serve as Israel’s first king.

When David heard that Saul was killed in a battle with the Philistines, David was grief-stricken. He even rewarded the men who saw to it that Saul received a decent burial (1 Samuel 31:11-13).

This is a quintessential example of what Jesus was talking about when He uttered the following words in the Sermon on the Mount:

"You have heard that it was said, 'You shall love your neighbor and hate your enemy.' But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who spitefully use you and persecute you… Matthew 5:43-44

Who, besides me, is thankful that Jesus loved us when we were His enemies (Romans 5:10)?

Who, besides me, needs to work on loving our enemies?
