'Seen' in the Bible

But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.

Am I not an apostle? am I not free? have I not seen Jesus Christ our Lord? are not ye my work in the Lord?

And that he was seen of Cephas, then of the twelve:

After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.

After that, he was seen of James; then of all the apostles.

And last of all he was seen of me also, as of one born out of due time.
