'Memory' in the Bible

Let them be before Jehovah continually, That he may cut off the memory of them from the earth;

They shall utter the memory of thy great goodness, And shall sing of thy righteousness.

The memory of the righteous is blessed; But the name of the wicked shall rot.

For the living know that they shall die: but the dead know not anything, neither have they any more a reward; for the memory of them is forgotten.
