C. F. Keil and Franz Delitzsch on 2 Samuel 12:18

2Sa 12:18

On the seventh day, when the child died, the servants of David were afraid to tell him of its death; for they said (to one another), “Behold, while the child was still living, we spoke to him, and he did not hearken to our voice; how should we say to him, now the child is dead, that he should do harm?” (i.e., do himself an injury in the depth of his anguish.)
