Gevurot Meyruach Hakodesh 1:23-26

And they put forward two anashim, Yosef Bar-Sabba, also called Justus, and Mattityahu. And having davened, they said, Adonoi, you have da'as of the levavot of Kol Bnei Adam. Therefore, show which of these two is your bechirah To take the place of this avodas kodesh ministry and Shlichus from which Yehudah turned aside to go to his own place. And they drew lots, and the lot fell to Mattityahu, and he was numbered with the Achad Asar of Moshiachʼs Shlichim.
