1 Samuel 18:1-11, 19:1-7
As soon as he had finished speaking to Saul, the soul of Jonathan was knit to the soul of David, and Jonathan loved him as his own soul. And Saul took him that day and would not let him return to his father’s house. Then Jonathan made a covenant with David, because he loved him as his own soul. And Jonathan stripped himself of the robe that was on him and gave it to David, and his armor, and even his sword and his bow and his belt. And David went out and was successful wherever Saul sent him, so that Saul set him over the men of war. And this was good in the sight of all the people and also in the sight of Saul’s servants.
As they were coming home, when David returned from striking down the Philistine, the women came out of all the cities of Israel, singing and dancing, to meet King Saul, with tambourines, with songs of joy, and with musical instruments. And the women sang to one another as they celebrated,
“Saul has struck down his thousands,
and David his ten thousands.”
And Saul was very angry, and this saying displeased him. He said, “They have ascribed to David ten thousands, and to me they have ascribed thousands, and what more can he have but the kingdom?” And Saul eyed David from that day on.
The next day a harmful spirit from God rushed upon Saul, and he raved within his house while David was playing the lyre, as he did day by day. Saul had his spear in his hand. And Saul hurled the spear, for he thought, “I will pin David to the wall.” But David evaded him twice.
…
And Saul spoke to Jonathan his son and to all his servants, that they should kill David. But Jonathan, Saul’s son, delighted much in David. And Jonathan told David, “Saul my father seeks to kill you. Therefore be on your guard in the morning. Stay in a secret place and hide yourself. And I will go out and stand beside my father in the field where you are, and I will speak to my father about you. And if I learn anything I will tell you.” And Jonathan spoke well of David to Saul his father and said to him, “Let not the king sin against his servant David, because he has not sinned against you, and because his deeds have brought good to you. For he took his life in his hand and he struck down the Philistine, and the LORD worked a great salvation for all Israel. You saw it, and rejoiced. Why then will you sin against innocent blood by killing David without cause?” And Saul listened to the voice of Jonathan. Saul swore, “As the LORD lives, he shall not be put to death.” And Jonathan called David, and Jonathan reported to him all these things. And Jonathan brought David to Saul, and he was in his presence as before.
John 15:9-15
As the Father has loved me, so have I loved you. Abide in my love. If you keep my commandments, you will abide in my love, just as I have kept my Father’s commandments and abide in his love. These things I have spoken to you, that my joy may be in you, and that your joy may be full.
“This is my commandment, that you love one another as I have loved you. Greater love has no one than this, that someone lay down his life for his friends. You are my friends if you do what I command you. No longer do I call you servants, for the servant does not know what his master is doing; but I have called you friends, for all that I have heard from my Father I have made known to you.
