And the men of Shechem set liers in wait for him in the top of
the mountains
Of Ebal and Gerizim, which were near Shechem, by the way of which he passed when he came to that city, and these they set there, either to slay him, or to seize his person, and bring him to them:
and they robbed all that came along that way by them;
that belonged to Abimelech and others also; and this they did to show their contempt of his government, and that they were no longer under it, and every man did what was right in his own eyes, as if they had no governor over them; though some think this was done to draw him thither to secure his subjects from such rapine and violence, that they might have an opportunity to lay hold upon him, or this they did on purpose to begin a civil war:
and it was told Abimelech;
that they lay in wait for him, and so he kept himself from them.
