Paul describes some of Jesus' post-resurrection appearances.
Paul, First Epistle to the Corinthians, 15:3-8 (Codex Sinaiticus)
For I delivered to you, among the first things, that which I also received; that Christ died for our sins, according to the Scriptures; and that he was buried; and that he rose from the dead on the third day, according to the Scriptures; and that he appeared to Cephas, then to the twelve. After that he appeared to more than five hundred brethren at once, of whom the greater part remain till now, but some have also fallen asleep. After that he appeared to James, after that to all the apostles. But, last of all, as to the one born out of due time, he appeared to me also. (KJV)
