John 1:27

27 he who comes after me, the thong of whose sandal I am not worthy to unloose.

John 1:27 In-Context

25 And they asked him and said to him, Why baptisest thou then, if thou art not the Christ, nor Elias, nor the prophet?

26 John answered them saying, I baptise with water. In the midst of you stands, whom ye do not know,

27 he who comes after me, the thong of whose sandal I am not worthy to unloose.

28 These things took place in Bethany, across the Jordan, where John was baptising.

29 On the morrow he sees Jesus coming to him, and says, Behold the Lamb of God, who takes away the sin of the world.
