Acts 1:23-26 NIV

[23] So they nominated two men: Joseph called Barsabbas (also known as Justus) and Matthias. [24] Then they prayed, “Lord, you know everyone’s heart. Show us which of these two you have chosen [25] to take over this apostolic ministry, which Judas left to go where he belongs.” [26] Then they cast lots, and the lot fell to Matthias; so he was added to the eleven apostles.
