And David sent messengers, and took her; and she came in unto him, and he lay with her; for she was purified from her uncleanness: and she returned unto her house.

Wesley's Notes

11:4 Took her - From her own house into his palace, not by force, but by persuasion. Lay with her - See how all the way to sin is down hill! When men begin, they cannot soon stop themselves.

King James Translators' Notes

for she...: or, and when she had purified herself, etc, she returned

Jamieson-Fausset-Brown Bible Commentary

4. David sent messengers, and took her-The despotic kings of the East, when they take a fancy for a woman, send an officer to the house were she lives, who announces it to be the royal pleasure she should remove to the palace. An apartment is there assigned to her; and if she is made queen, the monarch orders the announcement to be made that he has made choice of her to be queen. Many instances in modern Oriental history show the ease and despatch with which such secondary marriages are contracted, and a new beauty added to the royal seraglio. But David had to make a promise, or rather an express stipulation, to Bath-sheba, before she complied with the royal will (1Ki 1:13, 15, 17, 28); for in addition to her transcendent beauty, she appears to have been a woman of superior talents and address in obtaining the object of her ambition; in her securing that her son should succeed on the throne; in her promptitude to give notice of her pregnancy; in her activity in defeating Adonijah's natural expectation of succeeding to the crown; in her dignity as the king's mother-in all this we see very strong indications of the ascendency she gained and maintained over David, who, perhaps, had ample leisure and opportunity to discover the punishment of this unhappy connection in more ways than one [Taylor, Calmet].

Matthew Henry's Concise Commentary

11:1-5 Observe the occasions of David's sin; what led to it. 1. Neglect of his business. He tarried at Jerusalem. When we are out of the way of our duty, we are in temptation. 2. Love of ease: idleness gives great advantage to the tempter. 3. A wandering eye. He had not, like Job, made a covenant with his eyes, or, at this time, he had forgotten it. And observe the steps of the sin. See how the way of sin is down-hill; when men begin to do evil, they cannot soon stop. Observe the aggravations of the sin. How could David rebuke or punish that in others, of which he was conscious that he himself was guilty?
