2 Samuel 11:27b-12:15

David sent and brought her to his house, and she became his wife, and bore
him a son.

But the thing that David had done displeased the LORD,

And the LORD sent Nathan to David.  He came to him, and said to him,
"There were two men in a certain city, the one rich and the other poor.
The rich man had very many flocks and herds; but the poor man had nothing
but one little ewe lamb, which he had bought.  He brought it up, and it
grew up with him and with his children; it used to eat of his meager fare,
and drink from his cup, and lie in his bosom, and it was like a daughter
to him.  Now there came a traveler to the rich man, and he was loath to
take one of his own flock or herd to prepare for the wayfarer who had come
to him, but he took the poor man's lamb, and prepared that for the guest
who had come to him."  Then David's anger was greatly kindled against the
man.  He said to Nathan, "As the LORD lives, the man who has done this
deserves to die; he shall restore the lamb fourfold, because he did this
thing, and because he had no pity."

Nathan said to David, "You are the man!  Thus says the LORD, the God of
Israel: I anointed you king over Israel, and I rescued you from the hand
of Saul; I gave you your master's house, and your master's wives into your
bosom, and gave you the house of Israel and of Judah; and if that had been
too little, I would have added as much more.  Why have you despised the
word of the LORD, to do what is evil in his sight?  You have struck down
Uriah the Hittite with the sword, and have taken his wife to be your wife,
and have killed him with the sword of the Ammonites.  Now therefore the
sword shall never depart from your house, for you have despised me, and
have taken the wife of Uriah the Hittite to be your wife.  Thus says the
LORD: I will raise up trouble against you from within your own house; and
I will take your wives before your eyes, and give them to your neighbor,
and he shall lie with your wives in the sight of this very sun.  For you
did it secretly; but I will do this thing before all Israel, and before
the sun."  David said to Nathan, "I have sinned against the LORD."  Nathan
said to David, "Now the LORD has put away your sin; you shall not die.
Nevertheless, because by this deed you have utterly scorned the LORD, the
child that is born to you shall die."  Then Nathan went to his house.

The LORD struck the child that Uriah's wife bore to David, and it became
very ill.
