Mark 1:6~8 (NIV)

⁶ John wore clothing made of camel’s hair, with a leather belt around his waist, and he ate locusts and wild honey. 

⁷ And this was his message: “After me comes the one more powerful than I, the straps of whose sandals I am not worthy to stoop down and untie. 

⁸ I baptize you with water, but he will baptize you with the Holy Spirit.”
