Just to be clear, Paul literally made tents. The meaning of "tentmaking" that you quote came later by analogy with Paul.
I feel like if tent-making was such a prevalent profession, there'd be name derivatives from it
The Arabic surnames Kheyyam/Khayam/Khayami are all derived from the word for tent maker, Plachta is Polish, but more closely aligns with canvas-maker, mostly sails. And then theres Zeltman, which is German for tent man (which is ambiguous between "man who sells tents" and "man who lives in a tent")
> And then theres Zeltman, which is German for tent man (which is ambiguous between "man who sells tents" and "man who lives in a tent")
likely a bit of both!
