Exodus 37:3-5

Webster(i) 3 And he cast for it four rings of gold, to be set by the four corners of it; even two rings upon the one side of it, and two rings upon the other side of it. 4 And he made staffs of shittim wood, and overlaid them with gold. 5 And he put the staffs into the rings by the sides of the ark, to bear the ark.
