'Lord's' in the Bible

The captain of the Lord’s host said to Joshua, “Remove your sandals from your feet, for the place where you are standing is holy.” And Joshua did so.

If, however, the land of your possession is unclean, then cross into the land of the possession of the Lord, where the Lord’s tabernacle stands, and take possession among us. Only do not rebel against the Lord, or rebel against us by building an altar for yourselves, besides the altar of the Lord our God.
