'Right hand' in the Bible

Let us pass, I pray thee, through thy land: we will not pass through field or through vineyard, neither will we drink of the water of the wells: we will go along the king's highway; we will not turn aside to the right hand nor to the left, until we have passed thy border.

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