Exodus 34:6 And the Lord passed by before him, and proclaimed, The Lord, The Lord God, merciful and gracious, long-suffering, and abundant in goodness and truth, 7 Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear the guilty
[Patriarchs & Prophets pp 722] 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 message was sent him by the prophet, “The Lord also hath put away thy sin; thou shalt not die.” Yet justice must be maintained. The sentence of death was transferred from David to the child of his sin. Thus the king was given opportunity for repentance; while to him the suffering and death of the child, as a part of his punishment, was far more bitter than his own death could have been.
The prophet said, “Because by this deed thou hast given great occasion to the enemies of the Lord to blaspheme, the child also that is born unto thee shall surely die.” 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.
Psalms 103:6 The Lord executeth righteousness and judgment for all that are oppressed.
May God add His blessing to the study of His word. "Good night" and God bless!
