🔼The name Matthias in the Bible
There's only one man named Matthias in the Bible, although this name is very similar to that of Matthaios, or Matthew. Matthias was one of two candidates to replace Judas Iscariot; the other one was Joseph Barsabbas, also known as Justus (Acts 1:23). The lot fell to Matthias and although we may assume that he engaged his apostolic ministry with vigor, we never hear from him again.
🔼Etymology of the name Matthias
The name Matthias appears to be a transliteration of a Hebrew name, probably מאתיה (Mattaiah), which doesn't occur in the Hebrew Bible. This name would consist of two elements, the final one being יה (Yah) = יהו (Yahu) = יו (Yu), which in turn are abbreviated forms of the Tetragrammaton יהוה, YHWH, or Yahweh.
The first part of the name Matthias comes from the root-verb נתן (natan) meaning to give:
The name Matthias means Gift Of The Lord, or more specifically: Gift Of Yah.
