Mark 1:3-5

3 The voice of one crying in the wilderness, prepare the way of [the] Lord, make His paths straight.

4 John came baptizing in the wilderness and proclaiming the baptism of repentance for the remission of sins.

5 And all the land of Judea, and those of Jerusalem, went out to him and were all baptized by him in the Jordan River, confessing their sins.
