'King's' in the Bible

"Please let us pass through your 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 your border."

"Let me pass through your land: we will not turn aside into field, or into vineyard; we will not drink of the water of the wells: we will go by the king's highway, until we have passed your border."
