'Right hand' in the Bible

Let us pass, I pray thee, through thy country; we will not pass through fields, or through vineyards, neither will we drink water out of the wells: we will go by the king's road; we will not turn to the right hand nor to the left, until we have passed thy border.

Then the Angel of Jehovah went still further, and stood in a narrow place, where was no way to turn either to the right hand or to the left.
