Adam Clarke on Psalms 80:18

So wilt not we go back from thee - We shall no more become idolaters: and it is allowed on all hands that the Jews were never guilty of idolatry after their return from the Babylonish captivity.

Quicken us - Make us alive, for we are nearly as good as dead.

We will call upon they name - We will invoke thee. Thou shalt be for ever the object of our adoration, and the center of all our hopes.
