2 Samuel 4:5-6

King James Version

⁵ And the sons of Rimmon the Beerothite, Rechab and Baanah, went, and came about the heat of the day to the house of Ishbosheth, who lay on a bed at noon.

⁶ And they came thither into the midst of the house, as though they would have fetched wheat; and they smote him under the fifth rib: and Rechab and Baanah his brother escaped.
