6 And it came to pass as they came, when David returned from the slaughter of the Philistine, that the women came out of all the cities of Israel, singing and dancing, to meet king Saul, with tambours, with joy, and with triangles. 7 And the women answered [one another] as they played, and said, Saul hath smitten his thousands, And David his ten thousands. 8 And Saul was very wroth, and that saying was evil in his sight; and he said, They have ascribed to David ten thousands, but to me they have ascribed the thousands; and [what] is there more for him but the kingdom? 9 And Saul eyed David from that day and forward. 10 And it came to pass the next day that an evil spirit from God came upon Saul, and he prophesied in the midst of the house, but David played with his hand, as on other days; and the spear was in Saul's hand. 11 And Saul cast the spear, and thought, I will smite David and the wall. But David turned away from him twice.
12 And Saul was afraid of David, because Jehovah was with him, and had departed from Saul. 13 And Saul removed him from him, and made him his captain over a thousand; and he went out and came in before the people. 14 And David prospered in all his ways; and Jehovah was with him. 15 And Saul saw that he prospered well, and he stood in awe of him. 16 But all Israel and Judah loved David, for he went out and came in before them.

Commentary on 1 Samuel 18:6-11
(Read 1 Samuel 18:6-11)
David's troubles not only immediately follow his triumphs, but arise from them; such is the vanity of that which seems greatest in this world. It is a sign that the Spirit of God is departed from men, if, like Saul, they are peevish, envious, suspicious, and ill-natured. Compare David, with his harp in his hand, aiming to serve Saul, and Saul, with his javelin in his hand, aiming to slay David; and observe the sweetness and usefulness of God's persecuted people, and the barbarity of their persecutors. But David's safety must be ascribed to God's providence.
Commentary on 1 Samuel 18:12-30
(Read 1 Samuel 18:12-30)
For a long time David was kept in continual apprehension of falling by the hand of Saul, yet he persevered in meek and respectful behaviour towards his persecutor. How uncommon is such prudence and discretion, especially under insults and provocations! Let us inquire if we imitate this part of the exemplary character before us. Are we behaving wisely in all our ways? Is there no sinful omission, no rashness of spirit, nothing wrong in our conduct? Opposition and perverseness in others, will not excuse wrong tempers in us, but should increase our care, and attention to the duties of our station. Consider Him that endured contradiction of sinners against himself, lest ye be weary and faint in your minds, Hebrews 12:3. If David magnified the honour of being son-in-law to king Saul, how should we magnify the honour of being sons to the King of kings!
