'Age during' in the Bible

and the Life was manifested, and we have seen, and do testify, and declare to you the Life, the age-during, which was with the Father, and was manifested to us --

and this is the promise that He did promise us -- the life the age-during.

Every one who is hating his brother -- a man-killer he is, and ye have known that no man-killer hath life age-during in him remaining,

and this is the testimony, that life age-during did God give to us, and this -- the life -- is in His Son;

These things I did write to you who are believing in the name of the Son of God, that ye may know that life ye have age-during, and that ye may believe in the name of the Son of God.

and we have known that the Son of God is come, and hath given us a mind, that we may know Him who is true, and we are in Him who is true, in His Son Jesus Christ; this one is the true God and the life age-during!
