Michal

Boyd’s Bible Dictionary:

Daughter of Saul and wife of David
({vi 7558;7906}1 Sam. 14:49; 25:44; {vi 8096;8181}2 Sam. 3:14; 6:23).

Concise Bible Dictionary:

Younger daughter of Saul, and wife of David. She helped David to escape when her father sought his death. When David was being persecuted she was given as wife to Phaltiel; but when David came into power he demanded of Abner that she should be restored to him. She did not share David’s zeal for the Lord, for when he brought up the ark and danced in joy before it, she not only despised him in her heart but reproached him for it. On this account she was barren the rest of her days ({vi 7697-7705}1 Sam. 18:20-28; {vi 7718-7724}1 Sam. 19:11-17; 1 Sam. 25:44; {vi 8095-8096}2 Sam. 3:13-14; {vi 8174-8181}2 Sam. 6:16-23). In 2 Samuel 21:8, for “Michal,” it should probably be read “[the sister of] Michal,” that is, Merab, as in 1 Samuel 18:19. Michal is an instance of how altogether beyond the natural mind are the leadings of the Spirit of God (compare 1 Cor. 2:14).
