Hebrews 9:27 KJVS
[27] And as it is appointed unto men once to die, but after this the judgment:
Same principal with David's son...
2 Samuel 12:16-23 KJVS
[16] David therefore besought God for the child; and David fasted, and went in, and lay all night upon the earth. [17] And the elders of his house arose, and went to him, to raise him up from the earth: but he would not, neither did he eat bread with them. [18] And it came to pass on the seventh day, that the child died. And the servants of David feared to tell him that the child was dead: for they said, Behold, while the child was yet alive, we spake unto him, and he would not hearken unto our voice: how will he then vex himself, if we tell him that the child is dead? [19] But when David saw that his servants whispered, David perceived that the child was dead: therefore David said unto his servants, Is the child dead? And they said, He is dead. [20] Then David arose from the earth, and washed, and anointed himself, and changed his apparel, and came into the house of the Lord, and worshipped: then he came to his own house; and when he required, they set bread before him, and he did eat. [21] Then said his servants unto him, What thing is this that thou hast done? thou didst fast and weep for the child, while it was alive; but when the child was dead, thou didst rise and eat bread. [22] And he said, While the child was yet alive, I fasted and wept: for I said, Who can tell whether God will be gracious to me, that the child may live? [23] But now he is dead, wherefore should I fast? can I bring him back again? I shall go to him, but he shall not return to me.
