David mourns that Israelites have died in the battle. Do we mourn for the state of the church and our own hearts? He mourns for his friend Jonathan, and even for Saul who wanted to kill him! We pity our enemies because know we too are capable of great wickedness but that the Lord has saved us. The lying Amalekite is put to death for claiming to have killed Saul. This is a foretaste of the judgement to come. There is safety in Christ.
