"Sending for Abiathar the priest, the son of Ahimelech, “David inquired of the Lord, saying, If I pursue after this troop, shall I overtake them?” The answer was, “Pursue: for thou shalt surely overtake them, and shalt without fail recover all.” 1 Samuel 30:8 , R.V. PP 693.1"
"And David enquired at the Lord, saying, Shall I pursue after this troop? shall I overtake them? And he answered him, Pursue: for thou shalt surely overtake them, and without fail recover all."
Ellen White directly references 1 Samuel 30:8 in this passage.
"Advancing, they came upon an Egyptian slave apparently about to perish from weariness and hunger. Upon receiving food and drink, however, he revived, and they learned that he had been left to die by his cruel master, an Amalekite belonging to the invading force. He told the story of the raid and pillage; and then, having exacted a promise that he should not be slain or delivered to his master, he consented to lead David's company to the camp of their enemies. PP 693.3"
"And they found an Egyptian in the field, and brought him to David, and gave him bread, and he did eat; and they made him drink water;"
This is a direct reference to the story in 1 Samuel 30:11. EGW is retelling the biblical narrative.
"host was slain. Only a band of four hundred men, mounted upon camels, succeeded in making their escape. The word of the Lord was fulfilled. “David recovered all that the Amalekites had carried away: and David rescued his two wives. And there was nothing lacking to them, neither small nor great, neither sons nor daughters, neither spoil, nor anything that they had taken to them: David recovered all.” PP 693.4"
"And David recovered all that the Amalekites had carried away: and David rescued his two wives."
EGW directly quotes 1 Samuel 30:18.
"When David had invaded the territory of the Amalekites, he had put to the sword all the inhabitants that fell into his hands. But for the restraining power of God the Amalekites would have retaliated by destroying the people of Ziklag. They decided to spare the captives, desiring to heighten the honor of the triumph by leading home a large number of prisoners, and intending afterward to sell them as slaves. Thus, unwittingly, they fulfilled God's purpose, keeping the prisoners unharmed, to be restored to their husbands and fathers. PP 693.5"
"And David and his men went up, and invaded the Geshurites, and the Gezrites, and the Amalekites: for those nations were of old the inhabitants of the land, as thou goest to Shur, even unto the land of Egypt."
Both passages discuss David's interactions with the Amalekites, specifically his invasion of their territory. EGW provides additional interpretation of the events.
