1 Samuel 3:20-21
20 And all Israel from Dan to Beersheba knew that Samuel was established as a prophet of the Lord. 21 And the Lord appeared again at Shiloh, for the Lord revealed himself to Samuel at Shiloh by the word of the Lord.
1 Samuel 8:1
Israel Demands a King
8:1 When Samuel became old, he made his sons judges over Israel.
1 Samuel 8:3-9
3 Yet his sons did not walk in his ways but turned aside after gain. They took bribes and perverted justice.
4 Then all the elders of Israel gathered together and came to Samuel at Ramah 5 and said to him, “Behold, you are old and your sons do not walk in your ways. Now appoint for us a king to judge us like all the nations.” 6 But the thing displeased Samuel when they said, “Give us a king to judge us.” And Samuel prayed to the Lord. 7 And the Lord said to Samuel, “Obey the voice of the people in all that they say to you, for they have not rejected you, but they have rejected me from being king over them. 8 According to all the deeds that they have done, from the day I brought them up out of Egypt even to this day, forsaking me and serving other gods, so they are also doing to you. 9 Now then, obey their voice; only you shall solemnly warn them and show them the ways of the king who shall reign over them.”
1 Samuel 9:17
17 When Samuel saw Saul, the Lord told him, “Here is the man of whom I spoke to you! He it is who shall restrain my people.”
1 Samuel 10:1
Saul Anointed King
10:1 Then Samuel took a flask of oil and poured it on his head and kissed him and said, “Has not the Lord anointed you to be prince over his people Israel? And you shall reign over the people of theLord and you will save them from the hand of their surrounding enemies. And this shall be the sign to you that the Lord has anointed you to be prince over his heritage.
1 Samuel 13:1
Saul Fights the Philistines
13:1 Saul was . . . years old when he began to reign, and he reigned . . . and two years over Israel.
1 Samuel 13:13-14
13 And Samuel said to Saul, “You have done foolishly. You have not kept the command of the Lord your God, with which he commanded you. For then the Lord would have established your kingdom over Israel forever. 14 But now your kingdom shall not continue. The Lord has sought out a man after his own heart, and the Lord has commanded him to be prince over his people, because you have not kept what the Lord commanded you.”
1 Samuel 15:22-23
22 And Samuel said,
“Has the Lord as great delight in burnt offerings and sacrifices,
as in obeying the voice of the Lord?
Behold, to obey is better than sacrifice,
and to listen than the fat of rams.
23 For rebellion is as the sin of divination,
and presumption is as iniquity and idolatry.
Because you have rejected the word of the Lord,
he has also rejected you from being king.”
1 Samuel 16:1
David Anointed King
16:1 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 16:6-7
6 When they came, he looked on Eliab and thought, “Surely the Lord's anointed is before him.” 7 But the Lord said to Samuel, “Do not look on his appearance or on the height of his stature, because I have rejected him. For the Lord sees not as man sees: man looks on the outward appearance, but the Lord looks on the heart.”
1 Samuel 16:11-16
11 Then Samuel said to Jesse, “Are all your sons here?” And he said, “There remains yet the youngest, but behold, he is keeping the sheep.” And Samuel said to Jesse, “Send and get him, for we will not sit down till he comes here.” 12 And he sent and brought him in. Now he was ruddy and had beautiful eyes and was handsome. And the Lord said, “Arise, anoint him, for this is he.” 13 Then Samuel took the horn of oil and anointed him in the midst of his brothers. And the Spirit of the Lord rushed upon David from that day forward. And Samuel rose up and went to Ramah.
David in Saul's Service
14 Now the Spirit of the Lord departed from Saul, and a harmful spirit from the Lord tormented him. 15 And Saul's servants said to him, “Behold now, a harmful spirit from God is tormenting you.16 Let our lord now command your servants who are before you to seek out a man who is skillful in playing the lyre, and when the harmful spirit from God is upon you, he will play it, and you will be well.”
1 Samuel 16:18-19
18 One of the young men answered, “Behold, I have seen a son of Jesse the Bethlehemite, who is skillful in playing, a man of valor, a man of war, prudent in speech, and a man of good presence, and the Lord is with him.” 19 Therefore Saul sent messengers to Jesse and said, “Send me David your son, who is with the sheep.”
1 Samuel 16:21
21 And David came to Saul and entered his service. And Saul loved him greatly, and he became his armor-bearer. (ESV)
