What does 1 Samuel 18:26 mean?

When David heard what Saul wanted, he was happy to do it. Before the deadline, he and his men went out, killed two hundred Philistines, and brought back proof. David gave everything to Saul, just like he asked, so Saul gave his daughter Michal to David as his wife. 1 Samuel 18:26 - Modern Text Bible

(David goes above and beyond Saul's demand, showing both courage and commitment. Saul's plan to get David killed by the Philistines backfires, and David ends up marrying Michal.)
