With the account of the choosing of Israel's first king, Samuel included a rewriting of the specific duties outlined for royalty, probably as given in Deuteronomy 17:14-20. Monarch is presented as permissive, not imperative. Theocratic government means government by
the Lord. This need not be so in monarchy that did not rule under the Lord and according to the covenant law given in Deuteronomy 17:15-20.
"The king was:
Even God's chosen will experience opposition (1 Samuel 10:27 ). Saul's restraint is commendable - not acting in anger and hate.
They foolishly tried to make a covenant with the enemy (1 Samuel 11:1 ). There must be no compromise.
The enemy is always willing to make a covenant with us if we are willing to part with our spiritual eyesight.
Different manifestation but the same Holy Spirit (1 Corinthians 12:4 ). With one, a hot, burning indignation. Another, melted with tender compassion. The demonstrated severe threat of Saul rallied Israel to the fight. (1 Samuel 11:7-8 ). Saul's strategy
surprised the Ammonites completely (1 Samuel 11:9-11 ).
(1 Samuel 11:12-13; 10:27 ). It is a terrible thing when spiritual authority or leadership position is used to get back at others. Saul gave the praise and glory for the victory to God (1 Samuel 11:13 ). Thus Saul was fully accepted. Proof of a God-given leader
is in evidence here: a man moved by the Spirit does not defend self or use office for personal vengeance, he exalts and praises God. Saul began well. Would that he had continued well. We can and should.
Samuel's integrity as the last judge is affirmed (1 Samuel 12:1-15 ). Samuel charges them with their wrong of wanting a human king. Fear of the Lord and serving Him only, would save them from unhappy consequences. (1 Samuel 12:13-15 ). A miracle
storm confirmed that Samuel spoke with authority (1 Samuel 12:16-19 ). The storm came at the word of Samuel and during wheat harvest (May-June), not normal. Leadership should be able to say with Paul,
God is faithful and will accomplish his plans and purposes despite human failure (1 Samuel 12:22 ). He will do what pleases His reputation and character. Though disagreeing with Israel's action Samuel is committed to praying for them (1 Samuel 12:23 ),
and to teaching them. Walking carefully in truth with the Lord guarantees enjoyable fellowship. (1 Samuel 12:24-25 ).
The place of his anointing. The waiting test proved too much for him. Rather than wait on Samuel as was the instruction (1 Samuel 10:8 ). This arrangement prevented Saul acting on his own without God. He offered a burnt offering.
Not waiting for God's word through Samuel, this was his impatient sin. The offering was done no doubt, by the hand of Ahiah the priest at the king's insistence.
To act without God's word is foolish and sinful - it disqualifies leadership.
God reigns - Israel's king must not function independently of the law and the prophets. Such disobedience cost Saul the kingdom (1 Samuel 13:13 ). A description of the reduced army and lack of weaponry is given in 1 Samuel 13:19-23. But Saul had still double
Gideon's army - deliverance is in the Lord.
Jonathan in faith instigated an attack on the Philistines. He and his man who bore his armour slew 20 men. The Philistine raiders trembled as the earth quaked. Panic spread and Saul and his men attacked. When God is working, two dedicated men of faith are enough for
Him to use.
The Lord was giving the victory - the deserters returned and joined the battle (1 Samuel 14:21-22 ). Saul made an unwise vow which showed neglect of his own men and nearly cost the life of his own son (1 Samuel 14:24-45 ). What insight the incident
gives into the state of Saul's heart.
3.5. PRINCIPLES EXPLAINED (1 Samuel 10:25-27)
1 Samuel 10:25 "Then Samuel explained to the people the behavior of royalty, and wrote it in a book and laid it up before the Lord. ..."

To be chosen by God. 
To be an Israelite. 
Not to imitate royal courts of other nations, in his desire for horses, wives, and money. (1 Kings 10:28; 11:4 ). 
To have a copy of the law and obey it (Deuteronomy 17:18-19 ). "The original law was deposited in the central sanctuary Cf Deuteronomy 31:9" Ryrie
3.6. PROVING CONQUEST (1 Samuel 11:1-15)
3.6.1. THE AMMONITES BESIEGED JABESH-GILEAD
1 Samuel 11:2 "... 'On this condition I will make a covenant with you, that I may put out all your right eyes, and bring reproach on all Israel.'"
3.6.2. THE MESSAGE FROM JABESH CAME TO SAUL
1 Samuel 11:6 "And the Spirit of God came upon Saul when he heard those tidings, and his anger was kindled greatly."
3.6.3. SAUL WAS MAGNANIMOUS IN SPARING THE ONES WHO HAD OPPOSED HIS REIGN
3.7. PURPOSEFUL REMINDER (1 Samuel 12:1-25)
1 Thessalonians 1:5 "For our gospel did not come to you in word only, but also in power, and in the Holy Spirit and in much assurance, as you
know what kind of men we were among you for your sake."
3.8. PUNISHED DISOBEDIENCE (1 Samuel 13:1-23)
3.8.1. SAUL'S FIRST TESTING AND FAILURE WERE AT GILGAL
"He resorted to situation ethics rather than biblical ethics." NIV Study Bible
1 Samuel 13:13 "And Samuel said to Saul, Thou hast done foolishly: thou hast not kept the commandment of the LORD thy God, which he
commanded thee: ..."
3.8.2. SAUL VIOLATED A FUNDAMENTAL LAW OF THEOCRACY
3.9. POWERFUL FAITH (1 Samuel 14:1-23)
3.10. PERPLEXING VOWS (1 Samuel 14:24-52)
"He was ready to kill a son he loved for violating his command. But the king had knowingly violated the command of God. Instead of making Saul sensitive to the weakness of others, he was harsh with those
whose fault was less than his own. Saul fought valiantly against Israel's enemies (1 Samuel 14:47-48 ). He won many victories. But Saul was never able to win the most important victory of all: a victory over his own inner
weakness and flaws." Lawrence O. Richards - Teacher's Commentary page 210 - Victor Books - 1987, Scripture Press Publications, Inc.
