STRONGS NT 2467: ἴσημιἴσημι, found only in the Doric form
ἴσαμι,
to know; from which some derive the forms
ἴστε and
ἰσμεν, contracted from
ἰσατε and
ἰσαμεν; but these forms are more correctly derived from
εἰδῶ,
ἰσμεν equivalent to
ἴδμεν, etc. (cf. Alexander
Buttmann (1873) Ausf. Spr. i., p. 548); on the phrase
ἴστε (
R ἐστε)
γινώσκοντες,
Ephesians 5:5, see
γινώσκω, I. 2 b.
