This is the construct form of the same word for branch or bough, appearing in Judges 9:48 when Abimelech cuts 'a branch of trees' with an ax. The construct form links it to the following word 'trees,' creating the phrase 'branch of wood/trees.' Abimelech demonstrates the tactic by cutting a substantial bough, hoisting it on his shoulder, and commanding his men to do likewise quickly. These weren't small twigs but substantial branches heavy enough to be carried on the shoulder yet light enough for rapid collection. The construct form's grammatical relationship emphasizes the branches as tree-products, materials harvested for military destruction.
