'Right hand' in the Bible

Only take heart and be very strong; take care to do all the law which Moses my servant gave you, not turning from it to the right hand or to the left, so that you may do well in all your undertakings.

And the limit of Manasseh's land was from Asher to Michmethath, which is before Shechem; the line goes on to the right hand, to the people of En-tappuah.
