17 Saul said to David, "Here is my older daughter Merab. I will give her to you in marriage; only serve me bravely and fight the battles of the Lord." For Saul said to himself, "I will not raise a hand against him. Let the Philistines do that!" 18 But David said to Saul, "Who am I, and what is my family or my clan in Israel, that I should become the king's son-in-law?" 19 So[1] when the time came for Merab, Saul's daughter, to be given to David, she was given in marriage to Adriel of Meholah. 20 Now Saul's daughter Michal was in love with David, and when they told Saul about it, he was pleased. 21 "I will give her to him," he thought, "so that she may be a snare to him and so that the hand of the Philistines may be against him." So Saul said to David, "Now you have a second opportunity to become my son-in-law."
17 And Saul said to David, Behold my elder daughter Merab, her will I give thee to wife: only be thou valiant
17 Then Saul said to David, "Here is my elder daughter Merab. I will give her to you for a wife. Only be valiant for me and fight the Lord's battles." For Saul thought, "Let not my hand be against him, but let the hand of the Philistines be against him." 18 And David said to Saul, "Who am I, and who are my relatives, my father's clan in Israel, that I should be son-in-law to the king?" 19 But at the time when Merab, Saul's daughter, should have been given to David, she was given to Adriel the Meholathite for a wife. 20 Now Saul's daughter Michal loved David. And they told Saul, 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,
17 One day Saul said to David, "Here is Merab, my eldest daughter. I want to give her to you as your wife. Be brave and bold for my sake. Fight God's battles!" But all the time Saul was thinking, "The Philistines will kill him for me. I won't have to lift a hand against him." 18 David, embarrassed, answered, "Do you really mean that? I'm from a family of nobodies! I can't be son-in-law to the king." 19 The wedding day was set, but as the time neared for Merab and David to be married, Saul reneged and married his daughter off to Adriel the Meholathite. 20 Meanwhile, Saul's daughter Michal was in love with David. When Saul was told of this, he rubbed his hands in anticipation. "Ah, a second chance. I'll use Michal as bait to get David out where the Philistines will make short work of him." So again he said to David, "You're going to be my son-in-law." 21
17 Then Saul said to David, "Here is my older 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, "Let my hand not be against him, but let the hand of the Philistines be against him." 18 So David said to Saul, "Who am I, and what is my life or my father's family in Israel, that I should be son-in-law to the king?" 19 But it happened at the time when Merab, Saul's daughter, should have been given to David, that she was given to Adriel the Meholathite as a wife. 20 Now Michal, Saul's daughter, loved David. And they told Saul, and the thing pleased him. 21 So Saul said, "I will give her to him, that she may be a snare to him, and that the hand of the Philistines may be against him." Therefore Saul said to David a second time, "You shall be my son-in-law today."
17 One day Saul said to David, "I am ready to give you my older daughter, Merab, as your wife. But first you must prove yourself to be a real warrior by fighting the Lord 's battles." For Saul thought, "I'll send him out against the Philistines and let them kill him rather than doing it myself." 18 "Who am I, and what is my family in Israel that I should be the king's son-in-law?" David exclaimed. "My father's family is nothing!" 19 So when the time came for Saul to give his daughter Merab in marriage to David, he gave her instead to Adriel, a man from Meholah. 20 In the meantime, Saul's daughter Michal had fallen in love with David, and Saul was delighted when he heard about it. 21 "Here's another chance to see him killed by the Philistines!" Saul said to himself. But to David he said, "Today you have a second chance to become my son-in-law!"

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!
