{Seeing that} (epeid(885c)). Resumes from verse  21 . The
structure is not clear, but probably verses  23,24  form a sort
of conclusion or apodosis to verse  22  the protasis. The
resumptive, almost inferential, use of de like alla in the
apodosis is not unusual. {Ask for signs} (s(886d)eia aitousin). The
Jews often came to Jesus asking for signs ( Mt 12:38  16:1  Joh
6:30 ). {Seek after wisdom} (sophian z(8874)ousin). "The Jews
claimed to _possess_ the truth: the Greeks were seekers,
_speculators_" (Vincent) as in  Ac 17:23 .
