John Gill's  Exposition of the Bible 

Deuteronomy 2:27

Let me pass through thy land: I will go along by the high way, I will neither turn unto the right hand nor to the left.

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.
