2 Samuel 11:2

David was a man after God's own heart, and his lips had often sung of the Holy One, the future Christ. Yet as he walked upon his housetop he was fascinated by Bathsheba's nudity, and [he] added murder to adultery. Notice here how, even in his own house, a man cannot use his eyes without danger. Then repenting, he says to the Lord, "Against you, you only, have I sinned and done this evil in your sight." Being a king he feared no one else.

For blessed Jerome among others points out that Bathsheba manifested a type of the church or of human flesh and says that David bore the mark of Christ; this is clearly apt at many points. Just as Bathsheba when washing herself unclothed in the brook …

We have taken up the task of writing an apology for the present style of the prophet David, not because he needs this gift, who has excelled in such great merits and flourished in virtues, but because many people, reading the sequence of his deeds without considering the power of the Scriptures or the hidden mysteries, wonder how such a great prophet did not avoid the contagion of adultery first and then of murder. Therefore, it was our desire to review the history itself, which seems to have been exposed to sin.

For who, that hears of it, not only among believers but of unbelievers themselves also, does not utterly loathe this, that David walking upon his solar lusteth after Beershebah the wife of Uriah? Yet when he returns back from the battle, he bids him go home to wash his feet. Whereupon he answered at once, "The Ark of the Lord abideth in tents, shall I then take rest in my house?" David received him to his own board, and delivers to him letters, through which he must die. But of whom does David walking upon his solar bear a figure, saving of Him, concerning Whom it is written, "He hath set his tabernacle in the sun"? And what else is it to draw Beersheba to himself, but to join to Himself by a spiritual meaning the Law of the formal letter, which was united to a carnal people? For Beersheba is rendered 'the seventh well,' assuredly, in that through the knowledge of the Law, with spiritual grace infused, perfect wisdom is ministered unto us. And whom does Uriah denote, but the Jewish people, whose name is rendered by interpretation, 'My light from God?' Now forasmuch as the Jewish people is raised high by receiving the knowledge of the Law, it as it were glories 'in the light of God.' But David took from this Uriah his wife, and united her to himself, surely in that the strong-handed One, which is the rendering of 'David,' our Redeemer, shewed Himself in the flesh, whilst He made known that the Law spake in a spiritual sense concerning Himself, Hereby, that it was held by them after the letter, He proved it to be alienated from the Jewish people, and joined it to Himself, in that He declared Himself to be proclaimed by it.

Arose from off his bed - Where he had lain, and slept for some time. And the bed of sloth often proves the bed of lust. Washing herself - In a bath, which was in her garden.
