John Gill Commentary Judges 9:48

"And Abimelech gat him up to mount Zalmon, he and all the people that were with him; and Abimelech took an axe in his hand, and cut down a bough from the trees, and took it up, and laid it on his shoulder: and he said unto the people that were with him, What ye have seen me do, make haste, and do as I have done." — Judges 9:48 (ASV)

And Abimelech got him up to Mount Zalmon
A mountain near Shechem, and thought to be the same with Salmon in (Psalms 68:14) which seems to have had its name from the shade of the trees which grew upon it:

he and all the people that were with him ;
his whole army:

and Abimelech took an axe in his hand, and cut down a bough from the
trees ;
which grew upon Mount Zalmon:

and took it, and laid it on his shoulders ;
and carried it along with him:

and said unto the people that were with him, what you have seen me do,
make haste, and do as I have done ;
take an axe, and every man cut down a bough with all possible haste, and lay it on his shoulder.
