And the God of all grace, the one who has called you into his eternal (aiōnion | αἰώνιον | acc sg fem) glory in Christ, will, after you have suffered a little while, himself restore, confirm, strengthen, and establish you.
And may the God of peace, who, by the blood of the eternal (aiōniou | αἰωνίου | gen sg fem) covenant, brought up from the dead the great shepherd of the sheep, our Lord Jesus,
And for this reason he is the mediator of a new covenant, so that those who are called may receive the promised eternal (aiōniou | αἰωνίου | gen sg fem) inheritance, since a death has occurred that redeems them from the transgressions committed under that first covenant.
how much more will the blood of Christ, who through the eternal (aiōniou | αἰωνίου | gen sg neut) Spirit offered himself without blemish to God, purify our conscience from dead works to worship the living God!
he entered once for all into the Most Holy Place, not by means of the blood of goats and calves, but by means of his own blood, thus obtaining an eternal (aiōnian | αἰωνίαν | acc sg fem) redemption.
