Hi.
I'm checking verbs ayin"ayin as regards their Qal Past, third person plural.
And I find that usually the short form we find in Ps 55:22, in Gn 8:11 or in
Dt 2:16 is used (respectively, RKW, QLW and TMW).
But there is also the "normal" form "SFB:BW", they surrounded (for a case,
Js 6:15)
Does anyone on this list know why?
In other words: is there a rule, a law stating when, in which cases the
short form is to be used and not the long one (or the reverse)?
Maybe it is a mattern or rhythm?
