Abraham was also compelled to listen to Hagar’s complaints of abuse from Sarah. Abraham is in perplexity. If he seeks to redress the wrongs of Hagar he increases the jealousy and unhappiness of Sarah, his first and much-loved wife. Hagar flees from the face of Sarah. An angel of God meets her and comforts her and also reproves her for her haughty conduct, in bidding her return to her mistress and submit herself under her hands. (SR 78.1) MC VC

After the birth of Ishmael the Lord manifested Himself again to Abraham and said unto him, “I will establish My covenant between Me and thee and thy seed after thee in their generations for an everlasting covenant.” Genesis 17:2. Again the Lord repeated by His angel His promise to give Sarah a son, and that she should be a mother of many nations. Abraham did not yet understand the promise of God. His mind immediately rested upon Ishmael, as though through him would come the many nations promised, and he exclaimed, in his affection for his son, “O that Ishmael might live before Thee!” Genesis 17:18. (SR 78.2) MC VC

Again the promise is more definitely repeated to Abraham: “Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish My covenant with him for an everlasting covenant, and with his seed after him.” Genesis 17:19. Angels are sent the second time to Abraham on their way to destroy Sodom, and they repeat the promise more distinctly that “Sarah shall have a son.” Genesis 18:10. (SR 78.3) MC VC
