2 Samuel 11:2

And it came to pass, after the year was expired, at the time when kings go forth to battle, that David sent Joab, and his servants with him, and all Israel; and they destroyed the children of Ammon, and besieged Rabbah. But David tarried still at Jerusalem.

And David sent and enquired after the woman. And one said, Is not this Bath-sheba, the daughter of Eliam, the wife of Uriah the Hittite?

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.

And the woman conceived, and sent and told David, and said, I am with child.
