I've been off-list a while, but I just came across this question
<http://judaism.stackexchange.com/questions/14259> and figured folks
here might have some approach.

In short:  Usually the suffix “הם” HM is used to indicate “them” or
“their”, as in “אליהם” )LYHM or “כליהם” KLYHM. Sometimes, though, the
suffix used is “מו” MW, e.g., Deut 33:2 “וזרח משעיר למו”.

Is there any known grammatical difference between the two forms, or is
the -MW form usually taken to be simply a poetic style?
