Let me pass through thy land (See Gill on Numbers 21:22),
 I will go along by the highway;
 the king's highway, as in the place referred to, the public road: 
 I will neither turn to the right hand nor to the left;
 to go into his fields and vineyards, and gather the fruit, or tread down the corn and vines, or do any manner of mischief to them; see the above place.
