G3922–παρεισέρχομαι–pareiserchomai

And the law came in besides, that the trespass might abound; but where sin abounded, grace did abound more exceedingly:

παρεισῆλθεν, pareisēlthen “entered,”

and that because of the false brethren privily brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage:

παρεισῆλθον pareisēlthon “came in by stealth”
