to be a memorial to the sons of Israel, to the end that no stranger, who is not of the seed of Aaron, come near to burn incense before LORD, that he not be as Korah, and as his company, as LORD spoke to him by Moses.
And thou shall put the two stones upon the shoulder-pieces of the ephod, to be stones of memorial for the sons of Israel. And Aaron shall bear their names before LORD upon his two shoulders for a memorial.
