the sword of the children of Ammon. Now therefore the sword shall never depart from thine house.... Behold, I will raise up evil against thee out of thine own house, and I will take thy wives before thine eyes, and give them unto thy neighbor.... For thou didst it secretly; but I will do this thing before all Israel, and before the sun.” PP 721.4 The prophet's rebuke touched the heart of David; conscience was aroused; his guilt appeared in all its enormity. His soul was bowed in penitence before God. With trembling lips he said, “I have sinned against the Lord.” All wrong done to others reaches back from the injured one to God. David had committed a grievous sin, toward both Uriah and Bathsheba, and he keenly felt this. But infinitely greater was his sin against God. PP 722.1 Though there would be found none in Israel to execute the sentence of death upon the anointed of the Lord, David trembled, lest, guilty and unforgiven, he should be cut down by the swift judgment of God. But the m…
"Now therefore the sword shall never depart from thine house; because thou hast despised me, and hast taken the wife of Uriah the Hittite to be thy wife."
EGW quotes 2 Samuel 12:10 directly in the passage.
"When his child was stricken, David, with fasting and deep humiliation, pleaded for its life. He put off his royal robes, he laid aside his crown, and night after night he lay upon the earth, in heartbroken grief interceding for the innocent one suffering for his guilt. “The elders of his house arose, and went to him, to raise him up from the earth: but he would not.” Often when judgments had been pronounced upon persons or cities, humiliation and repentance had turned aside the blow, and the Ever-Merciful, swift to pardon, had sent messengers of peace. Encouraged by this thought, David persevered in his supplication so long as the child was spared. Upon learning that it was dead, he quietly submitted to the decree of God. The first stroke had fallen of that retribution which he himself had declared just; but David, trusting in God's mercy, was not without comfort. PP 722.3"
"David therefore besought God for the child; and David fasted, and went in, and lay all night upon the earth."
The EGW passage directly describes David's actions as described in 2 Samuel 12:16, including fasting and lying on the earth. It expands on the details, but the core event is the same.
"Very many, reading the history of David's fall, have inquired, “Why has this record been made public? Why did God see fit to throw open to the world this dark passage in the life of one so highly honored of Heaven?” The prophet, in his reproof to David, had declared concerning his sin, “By this deed thou hast given great occasion to the enemies of the Lord to blaspheme.” Through successive generations infidels have pointed to the character of David, bearing this dark stain, and have exclaimed in triumph and derision, “This is the man after God's own heart!” Thus a reproach has been brought upon religion, God and His word have been blasphemed, souls have been hardened in unbelief, and many, under a cloak of piety, have become bold in sin. PP 722.4"
"For the name of God is blasphemed among the Gentiles through you, as it is written."
EGW's statement about David's sin giving occasion for blasphemy echoes the sentiment in Romans 2:24, where the actions of believers cause God's name to be blasphemed among unbelievers. The connection is thematic, focusing on the negative impact of sin on God's reputation.
