I love what Jonathan did for David. He couldve followed his dad as most people do even if they are wrong. No wonder David called for his son
7 And David said to him, "Do not fear, for I will show you kindness for the sake of your father Jonathan, and I will restore to you all the land of Saul your father, and you shall eat at my table always." 8 And he paid homage and said, "What is your servant, that you should show regard for a dead dog such as I?" (2 Samuel 9:7-8, ESV)
