2 Samuel 14:30

set it on fire Partly in revenge for Absalom's refusal (cp. Judges 15:3-5), partly in the hope of bringing Joab to make a complaint in person.

The Sept. and some MSS. of the Vulg. add at the end of the verse: "And Joab's servants came to him with their clothes rent, and said, Absalom's servants have set thy field on fire." The words are not absolutely necessary to the sense, but they may have been accidentally omitted from the Heb. text.
