The holy God is just.
David who was convinced that
God who struck Nabal (1 Sam. 25:38)
Would also strike Saul (26:10) ...
Since David had done evil in the sight of the Lord (2 Sam. 11:27)
God struck the child of David and the Uriah’s wife Bathsheba (12:15)
So the child eventually died (v. 18).
After all, David not only experienced God striking Nabal and Saul
But also his own child.
The holy God is just.
