Biblical tale Muslim's greeting, first to last, in a low voice (7,3)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

SALAAM is a Muslim greeting, move the S to the end and surround it by BASS a low voice. With all the checkers in, I guessed it (my LOI) and then read about Balaam and his ass. Never having read the Bible, or been taught the story, the only hope was that I’d heard of the famous painting by Rembrandt. But I hadn’t. A quite silly story, which today would prompt animal welfare groups to ask for jail time for Balaam.
