Frequently, in halacha we see the rule of מעלין בקודש- loosely translated as "we go 'upwards' in holiness."

One example of this application is that one may use a parchment of tefillin to fix a Torah but not vice versa, because a Torah is considered 'holier' than tefillin.

Is there a Biblical verse for this principle? From where does this concept emanate?

Menachot 99a derives this principle from two biblical sources:

We don’t descend in holiness - from the fact that after Moshe began to erect the Mishkan, no one else (of lesser holiness) was allowed to help him complete it (Shemot 40:18). [This is following one explanation of Rashi there; Rashi himself gives two other explanations.]

We ascend in holiness - from the fire-pans of Korach’s followers which were turned into a covering for the altar (Bamidbar 17:3).
