You shall put the two stones on the [two] shoulder pieces of the ephod [of the high priest], as memorial stones for Israel; and Aaron shall bear their names on his two shoulders as a memorial before the Lord.

‘Now this day will be a memorial to you, and you shall keep it as a feast to the Lord; throughout your generations you are to celebrate it as an ordinance forever.

It shall serve as a sign to you on your hand (arm), and as a reminder on your forehead, so that the instruction (law) of the Lord may be in your mouth; for with a strong and powerful hand the Lord brought you out of Egypt.

Then the Lord said to Moses, “Write this in the book as a memorial and recite it to Joshua, that I will utterly wipe out the memory of Amalek [and his people] from under heaven.”

And he put them on the shoulder pieces of the ephod to be memorial stones (a remembrance) for the sons of Israel (Jacob), just as the Lord had commanded Moses.

Then God also said to Moses, “This is what you shall say to the Israelites, ‘The Lord, the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob (Israel), has sent me to you.’ This is My Name forever, and this is My memorial [name] to all generations.

I appeared to Abraham, to Isaac, and to Jacob (Israel) as God Almighty [El Shaddai], but by My name, Lord, I did not make Myself known to them [in acts and great miracles].

“You shall not take the name of the Lord your God in vain [that is, irreverently, in false affirmations or in ways that impugn the character of God]; for the Lord will not hold guiltless nor leave unpunished the one who takes His name in vain [disregarding its reverence and its power].
