2 Samuel 14:28-30

Young's Literal Translation

²⁸ And Absalom dwelleth in Jerusalem two years of days, and the face of the king he hath not seen;

²⁹ and Absalom sendeth unto Joab, to send him unto the king, and he hath not been willing to come unto him; and he sendeth again a second time, and he hath not been willing to come.

³⁰ And he saith unto his servants, `See, the portion of Joab [is] by the side of mine, and he hath barley there; go, and burn it with fire;' and the servants of Absalom burn the portion with fire.
