'Once' in the Bible

wherein ye once walked according to the course of this world, according to the prince of the powers of the air, of the spirit that now worketh in the sons of disobedience;

among whom we also all once lived in the lust of our flesh, doing the desires of the flesh and of the mind, and were by nature children of wrath, even as the rest:--

Wherefore remember, that once ye, the Gentiles in the flesh, who are called Uncircumcision by that which is called Circumcision, in the flesh, made by hands;

But now in Christ Jesus ye that once were far off are made nigh in the blood of Christ.

For ye were once darkness, but are now light in the Lord: walk as children of light
