Heb 2.14
επει ουν τα παιδια κεκοινωνηκεν αιματος και σαρκος και αυτος παραπλησιως μετεσχεν των αυτων ινα δια του θανατου καταργηση τον το κρατος εχοντα του θανατου τουτ εστιν τον διαβολον
epei oun ta paidia kekoinōnēken haimatos kai sarkos kai autos paraplēsiōs meteschen tōn autōn hina dia tou thanatou katargēsē ton to kratos echonta tou thanatou tout' estin ton diabolon
Since, then, the children have partaken of flesh and blood, in like manner He Himself also shared the same things, that through death He might render entirely idle the one having the power of death, that is, the devil;
καταργηση = ‘katargēsē’
‘katargēsē’ definition:
