"An attachment for David on the part of Michal, Saul's youngest daughter, afforded the king another opportunity to plot against his rival. Michal's hand was offered the young man on condition that evidence should be given of the defeat and slaughter of a specified number of their national foes. “Saul thought to make David fall by the hand of the Philistines,” but God shielded His servant. David returned a victor from the battle, to become the king's son-in-law. “Michal Saul's daughter loved him,” and the monarch, enraged, saw that his plots had resulted in the elevation of him whom he sought to destroy. He was still more assured that this was the man whom the Lord had said was better than he, and who should reign on the throne of Israel in his place. Throwing off all disguise, he issued a command to Jonathan and to the officers of the court to take the life of the one he hated. PP 652.1"
"And Saul said, I will give him her, that she may be a snare to him, and that the hand of the Philistines may be against him. Wherefore Saul said to David, Thou shalt this day be my son in law in the one of the twain."
The EGW passage recounts the story of Saul offering Michal to David as a snare, hoping the Philistines would kill him. This directly parallels the events described in 1 Samuel 18:21, making it a thematic parallel.
"Jonathan revealed the king's intention to David and bade him conceal himself while he would plead with his father to spare the life of the deliverer of Israel. He presented before the king what David had done to preserve the honor and even the life of the nation, and what terrible guilt would rest upon the murderer of the one whom God had used to scatter their enemies. The conscience of the king was touched, and his heart was softened. “And Saul sware, As the Lord liveth, he shall not be slain.” David was brought to Saul, and he ministered in his presence, as he had done in the past. PP 652.2"
"And Jonathan spake good of David unto Saul his father, and said unto him, Let not the king sin against his servant, against David; because he hath not sinned against thee, and because his works have been to thee-ward very good:"
The EGW passage describes Jonathan interceding with Saul on David's behalf, reminding him of David's good deeds. This aligns with the account in 1 Samuel 19:4, where Jonathan speaks favorably of David to Saul. The EGW passage expands on the details, but the core theme is the same.
"Again war was declared between the Israelites and the Philistines, and David led the army against their enemies. A great victory was gained by the Hebrews, and the people of the realm praised his wisdom and heroism. This served to stir up the former bitterness of Saul against him. While the young man was playing before the king, filling the palace with sweet harmony, Saul's passion overcame him, and he hurled a javelin at David, thinking to pin the musician to the wall; but the angel of the Lord turned aside the deadly weapon. David escaped and fled to his own house. Saul sent spies that they might take him as he should come out in the morning, and put an end to his life. PP 652.3"
"And Saul cast the javelin; for he said, I will smite David even to the wall with it. And David avoided out of his presence twice."
The EGW passage directly recounts the event described in 1 Samuel 18:11, including the detail of Saul casting a javelin at David. The wording is very similar.
