whom God set forth to be an atoning sacrifice, through faith in his blood, for a demonstration of his righteousness through the passing over of prior sins, in God's forbearance;

ἔνδειξιν endeixin “a showing forth”

to demonstrate his righteousness at this present time; that he might himself be just, and the justifier of him who has faith in Jesus.

ἔνδειξιν endeixin “showing forth”

Therefore show the proof of your love to them in front of the assemblies, and of our boasting on your behalf.

ἔνδειξιν endeixin “the proof”

and in nothing frightened by the adversaries, which is for them a proof of destruction, but to you of salvation, and that from God.

ἔνδειξις endeixis “a demonstration”
