NASB
"By referring to this, when you read you can understand my insight into the mystery of Christ,"
— Ephesians 3:4, NASB
“Whereby, when ye read, ye may understand my knowledge in the mystery of Christ)”
“whereby, when ye read, ye can perceive my understanding in the mystery of Christ; ”
“by which, when you read, you can perceive my understanding in the mystery of Christ;”
“When reading this, you will be able to understand my insight into the mystery of Christ”
“As you reading, may understand my knowledge in the mystery of Christ,”
“By the reading of which you will be clear about my knowledge of the secret of Christ;”
“Whereby, when ye read, ye may understand my knowledge in the mystery of Christ)”
For this reason I, Paul, the prisoner of Christ Jesus for the sake of you Gentiles--
if indeed you have heard of the stewardship of God's grace which was given to me for you;
that by revelation there was made known to me the mystery, as I wrote before in brief.
By referring to this, when you read you can understand my insight into the mystery of Christ,
which in other generations was not made known to the sons of men, as it has now been revealed to His holy apostles and prophets in the Spirit;
to be specific, that the Gentiles are fellow heirs and fellow members of the body, and fellow partakers of the promise in Christ Jesus through the gospel,
of which I was made a minister, according to the gift of God's grace which was given to me according to the working of His power.
