'Whereon' in the Bible

Every place whereon the sole of your foot shall tread have I given to you, as I said unto Moses.

And the captain of the LORD'S host said unto Joshua, Loose thy shoe from off thy foot; for the place whereon thou standest is holy. And Joshua did so.

And Moses sware on that day, saying, Surely the land whereon thy feet have trodden shall be thine inheritance, and thy children's for ever, because thou hast wholly followed the LORD my God.

And I gave you a land whereon thou hadst not labored, and cities which ye built not, and ye dwell therein; of vineyards and oliveyards which ye planted not do ye eat.
