Would it be reasonable to suggest that Heber is related to Hebron, not
far from the identified site of Qain (en-Nebi Yaqin) in Judges 5:24?
Judges 4:11, which is based on Judges 5 could not accept such a
southern location for Yael as he located the battle much more to the
north, and so he explained this by having a person Heber move to
the north. There he is described as a small tribal family separating
from a larger tribe. But in Judges 5:24 the two refer to place names.
This would also allow to divide the verse into some type of parallelism:
tbrk mn$ym y(l )$t xbr / [ )$t ] hqyny mn$ym b)hl tbrk
