For I know the plans I have for you,” declares the LORD, “plans to prosper you and not to harm you, plans to give you hope and a future. – Jeremiah 29:11 NIV
God know. See v. 2323 For they have done outrageous things in Israel; they have committed adultery with their neighbors’ wives and in my name have spoken lies, which I did not tell them to do. I know it and am a witness to it,” declares the LORD.
