'Memory' in the Bible

Sweet is the memory of the fish we had in Egypt for nothing, and the fruit and green plants of every sort, sharp and pleasing to the taste:

To be a sign, kept in memory for ever by the children of Israel, that no man who is not of the seed of Aaron has the right of burning spices before the Lord, so that he may not be like Korah and his band: as the Lord said to him by the mouth of Moses.

Then Moses and Eleazar the priest took the gold given by the captains of thousands and captains of hundreds, and took it into the Tent of meeting, to be a sign in memory of the children of Israel before the Lord.
