Psalm 89:20-28 and 1 Samuel 16:1-13

Psalm 89:20-28
20 Then you spoke in a vision to your holy ones, and you said: I have stationed help with the powerful one, and I have exalted the elect one from my people.
21 I have found my servant David. I have anointed him with my holy oil.
22 For my hand will assist him, and my arm will fortify him.
23 The enemy will have no advantage over him, nor will the son of iniquity be positioned to harm him.
24 And I will cut down his enemies before his face. And those who hate him, I will turn to flight.
25 And my truth and my mercy will be with him. And his horn will be exalted in my name.
26 And I will place his hand on the sea and his right hand on the rivers.
27 He will invoke me: "You are my father, my God, and the support of my salvation."
28 And I will make him the first-born, preeminent before the kings of the earth.
1 Samuel 16:1-13
1 And the Lord said to Samuel: "How long will you mourn for Saul, though I have rejected him, so that he would not reign over Israel? Fill your horn with oil and approach, so that I may send you to Jesse of Bethlehem. For I have provided a king from among his sons for myself."
2 And Samuel said: "How shall I go? For Saul will hear of it, and he will put me to death." And the Lord said: "You shall take, by your hand, a calf from the herd. And you shall say, 'I have arrived in order to immolate to the Lord.'
3 And you shall call Jesse to the sacrifice, and I will reveal to you what you should do. And you shall anoint whomever I will indicate to you."
4 Therefore, Samuel did just as the Lord told him. And he went to Bethlehem, and the elders of the city wondered. And meeting him, they said, "Is your arrival peaceful?"
5 And he said: "It is peaceful. I have arrived in order to immolate to the Lord. Be sanctified, and come with me to the sacrifice." Then he sanctified Jesse and his sons, and he called them to the sacrifice.
6 And when they had entered, he saw Eliab, and he said, "Could he be the Christ in the sight of the Lord?"
7 And the Lord said to Samuel: "You should not look with favor on his face, nor on the height of his stature. For I have rejected him. Neither do I judge by the appearance of a man. For man sees those things that are apparent, but the Lord beholds the heart."
8 And Jesse called Abinadab, and he brought him before Samuel. And he said, "Neither has the Lord chosen this one."
9 Then Jesse brought Shammah. And he said about him, "And the Lord has not chosen this one."
10 And so Jesse brought his seven sons before Samuel. And Samuel said to Jesse, "The Lord has not chosen any of these."
11 And Samuel said to Jesse, "Could the sons now be completed?" But he responded, "There still remains a little one, and he pastures the sheep." And Samuel said to Jesse: "Send and bring him. For we shall not recline to eat, until he arrives here."
12 Therefore, he sent and brought him. Now he was ruddy, and beautiful to behold, and with a stately face. And the Lord said, "Rise up, anoint him! For it is he."
13 Therefore, Samuel took the horn of oil, and he anointed him in the midst of his brothers. And the Spirit of the Lord was guiding David from that day and thereafter. And Samuel rose up, and he went away to Ramah.
