How many times does Matt appear in the bible?

Answer 1

It depends on whether you are looking for the name specifically, or his alternate name which was Levi, or variations on the name for different people:

"Matthew" is found at Matthew 9:9; 10:3; Mark 3:18; Luke 6:15; Acts 1:13.

["Levi" is found at Mark 2:14; Luke 5:27,29]

There are references in the genealogies of Jesus' ancestors:

"Matthat, which was the son of Levi" (Luke 3:24,29)

"Matthan the father of Jacob" (Matthew 1:15)

Finally, there is Matthias, the successor of Judas Iscariot (Acts 1:23,26).
