14 Some anxiety may be caused by a person’s past actions or failings. He may be plagued with guilt about something he did in the past, even many years ago. At times, King David felt that his ‘errors loomed over his head.’ He admitted: “My anguished heart makes me groan aloud.” (Ps. 38:3, 4, 8, 18) In that situation, what was the wise thing for David to do? What did he do? He trusted in Jehovah’s mercy and forgiveness. With conviction he said: “Happy is the one whose transgression is pardoned.”—Read Psalm 32:1-3, 5.
BLONDIE'S COMMENT
But what about the other repentant adulterers and murderers in the nation of Israel? Did God show them mercy and forgiveness? Why do we not read of any ordinary Israelites not being shown mercy?
Great comment from Blondie! God seems to forgive grave sins but somehow kills ordinary citizens for petty sins. Here are a few examples I found on COMMONSENSEATHEISM.COM

In Judges 14:11-19, Samson loses a bet for 30 sets of clothes. The spirit of God comes upon him and he kills 30 men to steal their clothes and pay off the debt.
