2 Samuel 12: 7,8:
7 And Nathan said to David, Thou art the man. Thus saith the LORD God of Israel, I anointed thee king over Israel, and I delivered thee out of the hand of Saul;8 And I gave thee thy master's house, and thy master's wives into thy bosom, and gave thee the house of Israel and of Judah; and if that had been too little, I would moreover have given unto thee such and such things.
God gave me curly hair, stocky stature, a best friend with freckles, five children, several dogs, a penchant for arguing, biting my nails, overeating, good health a love of hunting and fishing, and two husbands (not at the same time, fortunately).

8 And I gave thee thy master's house, and thy master's wives into thy bosom, and gave thee the house of Israel and of Judah; and if that had been too little, I would moreover have given unto thee such and such things.
But the problem is, GOD did NOT 'give permission' THROUGH Nathan.
Nathan was merely reminding David of what GOD had done.
