'Memorial' in the Bible

the man shall then bring his wife to the priest, and shall bring as an offering for her one-tenth of an ephah of barley meal; he shall not pour oil on it nor put frankincense on it, for it is a grain offering of jealousy, a grain offering of memorial, a reminder of iniquity.

The priest shall then have the woman stand before the Lord and let the hair of the woman’s head go loose, and place the grain offering of memorial in her hands, which is the grain offering of jealousy, and in the hand of the priest is to be the water of bitterness that brings a curse.

and the priest shall take a handful of the grain offering as its memorial offering and offer it up in smoke on the altar, and afterward he shall make the woman drink the water.

So Moses and Eleazar the priest took the gold from the captains of thousands and of hundreds, and brought it to the tent of meeting as a memorial for the sons of Israel before the Lord.
