"his right hand and on his left. And thus said Shimei when he cursed, Come out, come out, thou bloody man, and thou man of Belial. The Lord hath returned upon thee all the blood of the house of Saul, in whose stead thou hast reigned; and the Lord hath delivered the kingdom into the hand of Absalom thy son: and, behold, thou art taken in thy mischief, because thou art a bloody man.” PP 736.1"
"And thus said Shimei when he cursed, Come out, come out, thou bloody man, and thou man of Belial:"
The EGW passage directly quotes 2 Samuel 16:7, attributing the words to Shimei's curse against David. This is a clear and direct allusion.
"In David's prosperity Shimei had not shown by word or act that he was not a loyal subject. But in the affliction of the king this Benjamite revealed his true character. He had honored David upon his throne, but he cursed him in his humiliation. Base and selfish, he looked upon others as of the same character as himself, and, inspired by Satan, he wreaked his hatred upon him whom God had chastened. The spirit that leads man to triumph over, to revile or distress, one who is in affliction is the spirit of Satan. PP 736.2"
"A friend loveth at all times, and a brother is born for adversity."
The EGW passage illustrates the principle of true friendship being evident in adversity, contrasting Shimei's behavior with the ideal described in Proverbs 17:17. It's a thematic parallel where the EGW passage provides a specific example of the proverb's principle.
"Shimei's accusations against David were utterly false—a baseless and malignant slander. David had not been guilty of wrong toward Saul or his house. When Saul was wholly in his power, and he could have slain him, he merely cut the skirt of his robe, and he reproached himself for showing even this disrespect for the Lord's anointed. PP 736.3"
"And he said unto his men, The Lord forbid that I should do this thing unto my master, the Lord’s anointed, to stretch forth mine hand against him, seeing he is the anointed of the Lord."
The EGW passage directly references and expands upon the event described in 1 Samuel 24:6, specifically David's refusal to harm Saul, whom he recognized as the Lord's anointed.
Of David's sacred regard for human life, striking evidence had been given, even while he himself was hunted like a beast of prey. One day while he was hidden in the cave of Adullam, his thoughts turning back to the untroubled freedom of his boyhood life, the fugitive exclaimed, “Oh that one would give me drink of the water of the well of Bethlehem, which is by the gate!” 2 Samuel 23:13-17 . Bethlehem was at that time in the hands of the Philistines; but three mighty men of David's band broke through the guard, and brought of the water of Bethlehem to their master. David could not drink it. “Be it far from me,” he cried; “is not this the blood of the men that went in jeopardy of their lives?” And he reverently poured out the water as an offering to God. David had been a man of war, much of his life had been spent amid scenes of violence; but of all who have passed through such an ordeal, few indeed have been so little affected by its hardening, demoralizing influence as was David. PP 73…
"And three of the thirty chief went down, and came to David in the harvest time unto the cave of Adullam: and the troop of the Philistines pitched in the valley of Rephaim. And David was then in an hold, and the garrison of the Philistines was then in Beth–lehem. And David longed, and said, Oh that one would give me drink of the water of the well of Beth–lehem, which is by the gate! And the three mighty men brake through the host of the Philistines, and drew water out of the well of Beth–lehem, that was by the gate, and took it, and brought it to David: nevertheless he would not drink thereof, but poured it out unto the Lord. And he said, Be it far from me, O Lord, that I should do this: is not this the blood of the men that went in jeopardy of their lives? therefore he would not drink it. These things did these three mighty men."
Ellen White directly references 2 Samuel 23:13-17 in this passage.
"And David longed, and said, Oh that one would give me drink of the water of the well of Beth–lehem, which is by the gate!"
The EGW passage directly quotes 2 Samuel 23:15 and elaborates on the context and significance of the event.
