A correction/disclaimer:
BR:
<<Both Randal Buth and Peter Kirk have suggested holeket for a verb
in the second clause rather than a qatal>>
Actually, not. The opposite: I prefer halexa, as I first stated. "best"
means my recommendation.
(explaining an ambiguously incorrect form: halak:t, I wrote:
" -a- halexa [a.k.a.:'halekah'] is best, or holexet".
The holexet was an attempt at fixing/interpreting the student's consonantal
text.)
If a student wanted to start a story with a participle I would accept it,
though I myself wouldn't suggest it. Dream reports start with participles.
Qohelet could use them and some wisdom literature. Rabbi stories like them.
But your question has a point: I can't say if you ever get two same subject
clauses in such a biblical text. You certainly get participles/verbless
clauses followed by either vav ha-hippuk for the approriate temporal
direction.
