Mark 1:7-9

7 And he proclaimed, saying, One mightier than I comes after me, whose shoe-latchet I am unworthy to stoop down and untie.

8 I, indeed, have immersed you in water; but he will immerse you in the Holy Spirit.

9 At that time Jesus came from Nazareth of Galilee to the Jordan, and was immersed by John.
