Second Isaiah points out that tree wood has many uses. The most common form of Middle Eastern trees was the cedar or the oak tree, especially the holm oak. You have to let these trees grow strong among the many other trees in the forest. A cedar tree had to be nourished by rain. When it is chopped down, it could be used as fuel to warm oneself. You could also start a fire in order to bake bread.
Sirach continues with his personification of wisdom in the first person singular. Wisdom points out how she has grown tall like the various trees around Israel. First, she was tall like the cedar and cypress trees in the northern area of Lebanon and Hermon. Then she was like the palm trees on the west side of the Dead Sea in En-gedi and the rosebushes nearby in Jericho. Finally, she was tall like the various planted olive trees and the trees that were planted beside water. Wisdom was a like a tall tree, no matter where she was.
