‘ And Abimelech took himself up to Mount Zalmon, he and all the people who were with him, and Abimelech took an axe in his hand, and cut down a bough from the trees, and took it, and laid it on his shoulder, and said to the people who were with him, “What you have seen me do, be quick, and do as I have done.” '
Taking his people with him Abimelech climbed Mount Zalmon which was tree-covered, and was so fired up that he himself took an axe and cut a bough from the tree. Then he bid all his followers to do the same as quickly as they could. Mount Zalmon is unknown but may have been a part of either Ebal or Gerizim.
