G1732–ἔνδειξις–endeixis

Whom God hath set forth to be a propitiation, through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;

ἔνδειξιν endeixin “a showing forth”

To declare, I say, at this time his righteousness: that he may be just, and the justifier of him who believeth in Jesus.

ἔνδειξιν endeixin “showing forth”

Wherefore show ye to them, and before the churches, the proof of your love, and of our boasting on your behalf.

ἔνδειξιν endeixin “the proof”

And in nothing terrified by your adversaries: which is to them an evident token of perdition, but to you of salvation, and that from God.

ἔνδειξις endeixis “a demonstration”
