Paul Tripp's really helpful article has 6 observations from 1 Samuel. 

“Then Samuel went to Ramah, and Saul went up to his house in Gibeah of Saul. And Samuel did not see Saul again until the day of his death, but Samuel grieved over Saul. And the LORD regretted that he had made Saul king over Israel. The LORD said to Samuel, "How long will you grieve over Saul, since I have rejected him from being king over Israel? Fill your horn with oil, and go. I will send you to Jesse the Bethlehemite, for I have provided for myself a king among his sons." (1 Samuel 15:34-16:1)”
