Verse 11 describes what would happen: “Thus says the LORD, Behold, I will raise up evil against you out of your own house, and I will take your wives before your eyes, and give them unto your neighbor, and he shall lie with your wives in the sight of this sun.”
This is an astonishing account, and it shows how severely God will deal with this sin—a sin He considers against Him. God plainly stated that David’s wives would be raped publicly that very day—under “this sun.” The use of this term meant God would deal swiftly with what David did.
