'Memorial' in the Bible

Yea, in the way of thy judgments, O Jehovah, have we waited for thee; to thy name, even to thy memorial name , is the desire of our soul.

Unto them will I give in my house and within my walls a memorial and a name better than of sons and of daughters; I will give them an everlasting name, that shall not be cut off.

And behind the doors and the posts hast thou set up thy memorial: for thou hast uncovered thyself to another than me, and art gone up; thou hast enlarged thy bed, and made thee a covenant with them: thou lovedst their bed where thou sawest it.
