12You shall put the two stones on the shoulder straps of the ephod, to be stones of memorial for the children of Israel. Aaron shall bear their names before the LORD on his two shoulders for a memorial.

13You shall make settings of gold,

16It shall be square and folded double; a span shall be its length, and a span its width.
