“Which in other ages was not made knowen vnto the sonnes of men, as it is now reueiled vnto his holy Apostles and Prophets by the Spirit,”
1611 King James Version (KJV)
3:5 Which in other - In former, ages was not so clearly or fully made known to the sons of men - To any man, no, not to Ezekiel, so often styled, son of man; nor to any of the ancient prophets. Those here spoken of are New Testament prophets.
Eph 3:5 Which. The mystery. In other ages was not made known unto the sons of men. It was in past ages hidden from men, but now revealed by the Spirit to apostles and prophets. Not the old Hebrew prophets, but the prophets in the church. Some of the Hebrew prophets might have had a glimpse of Gentile salvation, but they did not understand their own language as well as we do in the light of the gospel.
