I will sing of steadfast love and justice;
to you, O LORD, I will make music.
I will ponder the way that is blameless.
Oh when will you come to me?
I will walk with integrity of heart
within my house;
I will not set before my eyes
anything that is worthless.
I hate the work of those who fall away;
it shall not cling to me.
A perverse heart shall be far from me;
I will know nothing of evil.
from Psalm 101
There was hard fighting against the Philistines all the days of Saul. And when Saul saw any strong man, or any valiant man, he attached him to himself.
from 1Samuel 14
Samuel said to Saul, “The LORD sent me to anoint you king over his people Israel; now therefore listen to the words of the LORD. Thus says the LORD of hosts, ‘I have noted what Amalek did to Israel in opposing them on the way when they came up out of Egypt. Now go and strike Amalek and devote to destruction all that they have. Do not spare them, but kill both man and woman, child and infant, ox and sheep, camel and donkey.’”
But Saul and the people spared Agag and the best of the sheep and of the oxen and of the fattened calves and the lambs, and all that was good, and would not utterly destroy them. All that was despised and worthless they devoted to destruction.
The word of the LORD came to Samuel: “I regret that I have made Saul king, for he has turned back from following me and has not performed my commandments.” And Samuel was angry, and he cried to the LORD all night. And Samuel rose early to meet Saul in the morning.
And Samuel came to Saul, and Saul said to him, “Blessed be you to the LORD. I have performed the commandment of the LORD.” And Samuel said, “What then is this bleating of the sheep in my ears and the lowing of the oxen that I hear?” Saul said, “They have brought them from the Amalekites, for the people spared the best of the sheep and of the oxen to sacrifice to the LORD your God, and the rest we have devoted to destruction.” Then Samuel said to Saul, “Stop! I will tell you what the LORD said to me this night.” And he said to him, “Speak.”
And Samuel said, “Though you are little in your own eyes, are you not the head of the tribes of Israel? The LORD anointed you king over Israel. And the LORD sent you on a mission and said, ‘Go, devote to destruction the sinners, the Amalekites, and fight against them until they are consumed.’ Why then did you not obey the voice of the LORD? Why did you pounce on the spoil and do what was evil in the sight of the LORD?” And Saul said to Samuel, “I have obeyed the voice of the LORD. I have gone on the mission on which the LORD sent me. I have brought Agag the king of Amalek, and I have devoted the Amalekites to destruction. But the people took of the spoil, sheep and oxen, the best of the things devoted to destruction, to sacrifice to the LORD your God in Gilgal.” 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.
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.”
Samuel said to Saul, “I will not return with you. For you have rejected the word of the LORD, and the LORD has rejected you from being king over Israel.” As Samuel turned to go away, Saul seized the skirt of his robe, and it tore. And Samuel said to him, “The LORD has torn the kingdom of Israel from you this day and has given it to a neighbor of yours, who is better than you. And also the Glory of Israel will not lie or have regret, for he is not a man, that he should have regret.”
Samuel did not see Saul again until the day of his death, but Samuel grieved over Saul. And the LORD regretted that he had made Saul king over Israel.
from 1Samuel 15
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.”
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.”
the LORD said, “Arise, anoint him, for this is he.” 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.
the Spirit of the LORD departed from Saul, and a harmful spirit from the LORD tormented him. And Saul’s servants said to him, “Behold now, a harmful spirit from God is tormenting you. 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.” So Saul said to his servants, “Provide for me a man who can play well and bring him to me.” 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.” Therefore Saul sent messengers to Jesse and said, “Send me David your son, who is with the sheep.”
Saul sent to Jesse, saying, “Let David remain in my service, for he has found favor in my sight.” And whenever the harmful spirit from God was upon Saul, David took the lyre and played it with his hand. So Saul was refreshed and was well, and the harmful spirit departed from him.
