6 As they were coming home, when David returned from killing the Philistine, the women came out of all the towns of Israel, singing and dancing, to meet King Saul, with tambourines, with songs of joy, and with musical instruments. 7 And the women sang to one another as they made merry, "Saul has killed his thousands, and David his ten thousands." 8 Saul was very angry, for this saying displeased him. He said, "They have ascribed to David ten thousands, and to me they have ascribed thousands; what more can he have but the kingdom?" 9 So Saul eyed David from that day on. 10 The next day an evil 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; 11 and Saul threw the spear, for he thought, "I will pin David to the wall." But David eluded him twice.
12 Saul was afraid of David, because the Lord was with him but had departed from Saul. 13 So Saul removed him from his presence, and made him a commander of a thousand; and David marched out and came in, leading the army. 14 David had success in all his undertakings; for the Lord was with him. 15 When Saul saw that he had great success, he stood in awe of him. 16 But all Israel and Judah loved David; for it was he who marched out and came in leading them. 17 Then Saul said to David, "Here is my elder daughter Merab; I will give her to you as a wife; only be valiant for me and fight the Lord's battles." For Saul thought, "I will not raise a hand against him; let the Philistines deal with him." 18 David said to Saul, "Who am I and who are my kinsfolk, my father's family in Israel, that I should be son-in-law to the king?" 19 But at the time when Saul's daughter Merab should have been given to David, she was given to Adriel the Meholathite as a wife. 20 Now Saul's daughter Michal loved David. Saul was told, and the thing pleased him. 21 Saul thought, "Let me give her to him that she may be a snare for him and that the hand of the Philistines may be against him." Therefore Saul said to David a second time, "You shall now be my son-in-law." 22 Saul commanded his servants, "Speak to David in private and say, "See, the king is delighted with you, and all his servants love you; now then, become the king's son-in-law.' " 23 So Saul's servants reported these words to David in private. And David said, "Does it seem to you a little thing to become the king's son-in-law, seeing that I am a poor man and of no repute?" 24 The servants of Saul told him, "This is what David said." 25 Then Saul said, "Thus shall you say to David, "The king desires no marriage present except a hundred foreskins of the Philistines, that he may be avenged on the king's enemies.' " Now Saul planned to make David fall by the hand of the Philistines. 26 When his servants told David these words, David was well pleased to be the king's son-in-law. Before the time had expired, 27 David rose and went, along with his men, and killed one hundred of the Philistines; and David brought their foreskins, which were given in full number to the king, that he might become the king's son-in-law. Saul gave him his daughter Michal as a wife. 28 But when Saul realized that the Lord was with David, and that Saul's daughter Michal loved him, 29 Saul was still more afraid of David. So Saul was David's enemy from that time forward. 30 Then the commanders of the Philistines came out to battle; and as often as they came out, David had more success than all the servants of Saul, so that his fame became very great.

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!
