'Memorial' in the Bible

then that man is to bring his wife to the priest along with an offering for her consisting of a tenth of an ephah of barley flour. He is not to pour oil or set frankincense over it, because it's to be a jealousy offering, a memorial offering that will serve as a reminder of iniquity.

The priest is to have the woman stand in the LORD's presence, uncover her head, and put the grain offering as a memorial, a reminder of jealousy, into her hands. The priest is also to have in his hand the contaminated water that carries a curse.

The priest is to take a handful of grain from the memorial and offer a sacrifice on the altar, after which he is to have the woman drink the water.

At the beginning of the month, during your time of rejoicing at the appointed place, sound the trumpet over your burnt offering, then sacrifice your peace offering, since they are to be your memorial before the LORD your God. I am the LORD your God."

to serve as a memorial to the Israelis, a reminder that no unauthorized person, who isn't a descendant of Aaron, is to attempt to burn incense in the LORD'S presence, so that he may not become like Korah and his group, just as the LORD had spoken by the authority of Moses.

Moses and Eleazar took the gold from the captains of thousands and hundreds and brought it to the Tent of Meeting, to serve as a memorial to the Israelis in the LORD's presence.
