Is it a matter of dikduk, Wolf?
If so, then there should be a clear correct answer.
What do you say before Vidui on Yom Kippur- “al tis’aleim mit’chinaseinu,” or “al tis’alam …” ??
I’ve seen both in different machzorim.
Is it possible it is a matter of interpretation or minhag?
(I’ve been told to say “morid ha’geshem” but I have heard “ha’gashem” with a kamatz, and I’ve seen it in siddurim.)
