Sh’mu’el Alef 16:1-3 Now the L-RD said to Sh’mu’el, "How long will you grieve over Sha’ul, since I have rejected him from being king over Israel? Fill your horn with oil, and go; I will send you to Yishai the Beit-Lachmi (Beit-Lechemite), for I have selected a king for Myself among his sons." But Sh’mu’el said, "How can I go? When Sha’ul hears of it, he will kill me." And the L-RD said, "Take a heifer with you, and say, 'I have come to sacrifice to the L-RD.' "And you shall invite Yishai to the sacrifice, and I will show you what you shall do; and you shall anoint for Me the one whom I designate to you."
Sha’ul was unstable and Sh’mu’el knew it. He did not want to be subject to Sha’ul’s revenge should he find out the purpose of his trip to Beit-Lechem.
Sh’mu’el Alef 16:4 So Sh’mu’el did what the L-RD said, and came to Beit-Lechem. And the elders of the city came trembling to meet him and said, "Do you come in peace?"
The elders of the city must have wondered of Sh’mu’el had come to judge them. Remember in the previous chapter Sh’mu’el poured out G-d’s wrath on Agag by cutting him to pieces. I am sure this would have be still on their minds.
Sh’mu’el Alef 16:5-7 And he said, "In peace; I have come to sacrifice to the L-RD. Consecrate yourselves and come with me to the sacrifice." He also consecrated Yishai and his sons, and invited them to the sacrifice. Then it came about when they entered, that he looked at Eli’av and thought, "Surely the L-rd's anointed is before Him." But the L-RD said to Sh’mu’el, "Do not look at his appearance or at the height of his stature, because I have rejected him; for G-d sees not as man sees, for man looks at the outward appearance, but the L-RD looks at the heart."
It would take spiritual insight to know whom the L-rd would choose. He obviously was not a tall man like Sha’ul. The same could be said of the true Messiah and our King. There was nothing in his appearance that would make us think He was anything special.
Yesha’yahu (Isaiah) 53:1-3 Who has believed our report? And to whom has the arm of the L-RD been revealed? For He shall grow up before Him as a tender plant, and as a root out of dry ground. He has no form or comeliness; and when we see Him, There is no beauty that we should desire Him. He is despised and rejected by men, A Man of sorrows and acquainted with grief. And we hid, as it were, our faces from Him; He was despised, and we did not esteem Him.
Sh’mu’el Alef 16:8-11a Then Yishai called Avinadav, and made him pass before Sh’mu’el. And he said, "Neither has the L-RD chosen this one." Next Yishai made Shammah pass by. And he said, "Neither has the L-RD chosen this one." Thus Yishai made seven of his sons pass before Sh’mu’el. But Sh’mu’el said to Yishai, "The L-RD has not chosen these." And Sh’mu’el said to Yishai, "Are these all the children?" And he said, "There remains yet the youngest, and look, he is tending the sheep."
He is tending the sheep. What makes a good leader? One who cares for and watches over sheep. This analogy was used by Yeshua himself and for good reason. The duties of a shepherd are in many ways the same duties of a good leader. He cares for the people and watches over them and wants to provide for their needs and also wants to protect them from harm. David was good at protecting his father’s sheep, which would prepare him for protecting G-d’s people. David would also have lived a life of loneliness and solitude while tending the sheep. Solitude can nurture a man and makes him and individualist whom is willing to rule. There is an expression “it is lonely at the top”. This is often true, a king doesn’t always know who is really on his side, who is really loyal and trustworthy. Loneliness can make a man or break him. How did David respond? He remained faithful and did his duty without complaint. His character grew from the little things to bigger and bigger things. We are never alone if we use this time with G-d. He is our hiding place and will be our companion in lonely times. The L-rd would use David’s skills as a shepherd to become King. If, with G-d’s help, we can take care of things even though they may seem unimportant or small. G-d will soon give you responsibility to take care of the bigger things. Yeshua would spend His time alone in the wilderness to be tested also. Yeshua is our shepherd and will be the King of Israel too.
Yochanan (John) 10:11-16 "I am the good shepherd; the good shepherd lays down His life for the sheep. "He who is a hireling, and not a shepherd, who is not the owner of the sheep, look the wolf coming, and leaves the sheep, and flees, and the wolf snatches them, and scatters them. "He flees because he is a hireling, and is not concerned about the sheep. "I am the good shepherd; and I know My own, and My own know Me, even as the Father knows Me and I know the Father; and I lay down My life for the sheep. "And I have other sheep, which are not of this fold; I must bring them also, and they shall hear My voice; and they shall become one flock with one shepherd.
Revelation 7:16 "They shall hunger no more, neither thirst anymore; neither shall the sun beat down on them, nor any heat; for the Lamb in the center of the throne shall be their shepherd, and shall guide them to springs of the water of life; and G-d shall wipe every tear from their eyes. "
Sh’mu’el Alef 16:11b-12 Then Sh’mu’el said to Yishai, "Send and bring him; for we will not sit down until he comes here." So he sent and brought him in. Now he was ruddy (red), with beautiful eyes and a handsome appearance. And the L-RD said, "Arise, anoint him; for this is he."
One could also say Yeshua had incredible eyes and a ruddy appearance.
Revelation 19:11-13 And I saw heaven opened; and look, a white horse, and He who sat upon it is called Faithful and True; and in righteousness He judges and wages war. And His eyes are a flame of fire, and upon His head are many diadems; and He has a name written upon Him, which no one knows except Himself. And He is clothed with a robe dipped in blood; and His name is called The Word of G-d.
Sh’mu’el Alef 16:13-16 Then Sh’mu’el took the horn of oil and anointed him in the midst of his brothers; and the Spirit of the L-RD came mightily upon David from that day forward. And Sh’mu’el arose and went to Ramah. Now the Spirit of the L-RD departed from Sha’ul, and an evil spirit from the L-RD terrorized him. Sha’ul's servants then said to him, "Look now, an evil spirit from G-d is terrorizing you. Let our lord now command your servants who are before you. Let them seek a man who is a skillful player on the harp; and it shall come about when the evil spirit from G-d is on you, that he shall play the harp with his hand, and you will be well."
The Spirit of the L-rd also known as “Ruach HaKodesh” would come upon a person in the Tanakh period to enable them to do a particular job. He would leave them when the job was done.
The idea of G-d sending an evil spirit to someone is strange but that is what happened. G-d could have sent an evil spirit for the purpose of bringing David to Sha’ul. G-d would also bless them both through each other. Sha’ul would then be soothed by David’s playing of the harp and David would be given higher status and later Sha’ul’s daughter.
Sh’mu’el Alef 16:17-22 So Sha’ul said to his servants, "Provide for me now a man who can play well, and bring him to me." Then one of the young men answered and said, "Look, I have seen a son of Yishai the Beit-Lechemite who is a skillful musician, a mighty man of valor, a warrior, one prudent in speech, and a handsome man; and the L-RD is with him." So Sha’ul sent messengers to Yishai, and said, "Send me your son David who is with the flock." And Yishai took a donkey loaded with bread and a jug of wine and a young goat, and sent them to Sha’ul by David his son. Then David came to Sha’ul and attended him, and Sha’ul loved him greatly; and he became his armor bearer. And Sha’ul sent to Yishai, saying, "Let David now stand before me; for he has found favor in my sight."
You can see the L-rd’s hand in this. David is recommended to be placed into Sha’ul’s inner circle. This gives David the perfect opportunity to observe how the government is run.
Sh’mu’el Alef 16:23 So it came about whenever the evil spirit from G-d came to Sha’ul, David would take the harp and play it with his hand; and Sha’ul would be refreshed and be well, and the evil spirit would depart from him.
David wrote many of the psalms. They can be a comfort to read when we go through hard times.
