2 Samuel 3:24-26

Amplified Bible

²⁴ Then Joab came to the king and said, “What have you done? Behold, Abner came to you; why did you send him away, so that he is already gone? ²⁵ You know Abner the son of Ner, that he [only] came to deceive you [with flattering words] and to learn of your going out and coming in, and to find out what you are doing.”
