In that case, we should refer to a delayed bris as "shelo be'itah"
rather than "shelo bizmanah".  But leshon Chazal is "shelo bizmanah",
e.g. Shabbat 132b.  Perhaps this is a chiluk in leshon mikra which
was lost in leshon Chazal, and was recovered in the modern era?
Did Chazal even use "eis", when not quoting or referring to a pasuk?
In a very cursory search, I only came across two such instances in
mishnayot, one of which seems to be an archaic formula.
