Note 1 at Acts 1:3: The phrase "infallible proofs" comes from one Greek word, "tekmerion." The only time this word is used in the Bible is in this verse and it is stressing the surety of the proofs that attested the resurrection of Jesus. The word "proof" is so strong that it needs no further description, therefore, the addition of "infallible" is surely underscoring that there could be no reasonable argument against the resurrection of Jesus.

Indeed, there is more historical evidence of the life and resurrection of Jesus than of any other person in history. For a person to believe that either the life or resurrection of Jesus is a myth is intentional ignorance (2 Pet. 3:5).

Note 2 at Acts 1:3: There are eight recorded appearances of Jesus to His disciples during these forty days. The first six of these appearances are recorded in order in footnote 9 at Jn. 21:14, page 559. The seventh appearance of Jesus was to His disciples at a mountain in Galilee (Mt. 28:16). His last appearance to His disciples was when He was received up to the Father which was recorded here and in Mark 16:19 and Luke 24:50-53.

There is one other mention of Jesus appearing to over 500 brethren at one time in 1 Corinthians 15:6. We have not included this instance as a ninth appearance because of the probability that this is descriptive of the same appearance that Matthew recorded on the mountain in Galilee or this account of His ascension.
