1 Samuel 13:7-14 And some of the Hebrews crossed over the Jordan to the land of Gad and Gilead. As for Saul, he was still in Gilgal, and all the people followed him trembling. Then he waited seven days, according to the time set by Samuel. But Samuel did not come to Gilgal; and the people were scattered from him. So Saul said, "Bring a burnt offering and peace offerings here to me." And he offered the burnt offering. Now it happened, as soon as he had finished presenting the burnt offering, that Samuel came; and Saul went out to meet him, that he might greet him. And Samuel said, "What have you done?" Saul said, "When I saw that the people were scattered from me, and that you did not come within the days appointed, and that the Philistines gathered together at Michmash, then I said, "The Philistines will now come down on me at Gilgal, and I have not made supplication to the LORD." Therefore I felt compelled, and offered a burnt offering." And Samuel said to Saul, "You have done foolishly. You have not kept the commandment of the LORD your God, which He commanded you. For now the LORD would have established your kingdom over Israel forever. But now your kingdom shall not continue. The LORD has sought for Himself a man after His own heart, and the LORD has commanded him to be commander over His people, because you have not kept what the LORD commanded you."
1 Samuel 16:1 Now the LORD said to Samuel, “How long will you mourn for Saul, seeing I have rejected him from reigning over Israel? Fill your horn with oil, and go; I am sending you to Jesse the Bethlehemite. For I have provided Myself a king among his sons.”
1 Samuel 10:21-24 When he had caused the tribe of Benjamin to come near by their families, the family of Matri was chosen. And Saul the son of Kish was chosen. But when they sought him, he could not be found. Therefore they inquired of the LORD further, “Has the man come here yet?” And the LORD answered, “There he is, hidden among the equipment.” So they ran and brought him from there; and when he stood among the people, he was taller than any of the people from his shoulders upward. And Samuel said to all the people, “Do you see him whom the LORD has chosen, that there is no one like him among all the people?” So all the people shouted and said, “Long live the king!”
1 Samuel 15:17 So Samuel said, 'When you were little in your own eyes, were you not head of the tribes of Israel? And did not the LORD anoint you king over Israel?
1 Samuel 15:12 So when Samuel rose early in the morning to meet Saul, it was told Samuel, saying, “Saul went to Carmel, and indeed, he set up a monument for himself; and he has gone on around, passed by, and gone down to Gilgal.”
