'Memorial' in the Bible

“This day is to be a memorial for you, and you must celebrate it as a festival to the Lord. You are to celebrate it throughout your generations as a permanent statute.

Fasten both stones on the shoulder pieces of the ephod as memorial stones for the Israelites. Aaron will carry their names on his two shoulders before the Lord as a reminder.

He fastened them on the shoulder pieces of the ephod as memorial stones for the Israelites, just as the Lord had commanded Moses.
