Midrasch zu Jeschijahu 56:5

Another comment on A good name is better than precious oil. A good name increases (among people), while precious oil descends. A good name arises, as it is written: And I will make of thee a great nation, and I will bless thee and make thy name great (Gen. 12:2), while precious oil flows downward, as it is said: It is like the precious oil upon the head (Ps. 133:2). Precious oil is transitory, while a good name is everlasting, as is said: May his name endure forever; may his name be continued as long as the sun (ibid. 72:17). This was said in reference to the prophets and the wise men. Precious oil may be destroyed, but a good name is indestructible, as it is said: I will give them an everlasting memorial, that they shall not be cut off (Isa. 56:5).

(Ib. ib. 6) Now there were among these, of the children of Judah, etc. R. Elazar said: "All of them were of the tribe of Judah." But Samuel b. Nachmeni said: "Only Daniel was of Judah; but Chananyah, Mishael and Azaryah were of other tribes." What means (Is. 56, 5) I will indeed give unto them … an everlasting name? R. Tanchun said: "Bar Kappara lectured in Sepphorias that this refers to the book of Daniel, which is named after him."
