Luke 3:16

16 John answered, and said [saying] to all men, [Soothly] I baptize you in water; but a stronger than I shall come after me, of whom I am not worthy to unbind the lace of his shoes [of whose I am not worthy to unbind the thong of his shoes]; he shall baptize you in the Holy Ghost and fire.

Luke 3:16 Meaning and Commentary

Luke 3:16

John answered, saying unto them all
For some of them might not only so think in their hearts, but express with their mouths the apprehension they had of him; and might put the question to him, as the priests and Levites from Jerusalem afterwards did; or he might know the secret thoughts of their hearts by divine revelation; or be apprized by his disciples of the private sentiments of the people concerning him: and therefore, to put them out of doubt, and that he might not have an honour conferred on him, which did not belong to him, he addressed himself, in a very public manner, to the whole multitude, in the hearing of them all: though the word "all" is left out in the Syriac and Persic versions, but rightly retained in others, being in all copies, and having a considerable emphasis on it: and said the following words.

I indeed baptize you with water;
Matthew adds "unto repentance"; upon the profession of repentance:

but one mightier than I cometh;
that is, after me;
as Matthew records it:

the latchet of whose shoes I am not worthy to unloose;
neither to bear his shoes after him, as Matthew says, nor to untie his shoe string, or unbuckle his shoe, both which were menial actions with the Jews: he shall baptize you with the Holy Ghost, and with fire; as he did some of their nation, his own disciples, on the day of pentecost; (See Gill on Matthew 3:11)

Luke 3:16 In-Context

14 And [the] knights asked him, and said, What shall also we do [Forsooth and the knights asked him, saying, What shall and we do]? And he said to them, Smite ye wrongfully no man, neither make ye false challenge, and be ye satisfied with your wages [and be satisfied with your wages].

15 When all the people guessed, and all men thought in their hearts of John, lest peradventure he were Christ,

16 John answered, and said [saying] to all men, [Soothly] I baptize you in water; but a stronger than I shall come after me, of whom I am not worthy to unbind the lace of his shoes [of whose I am not worthy to unbind the thong of his shoes]; he shall baptize you in the Holy Ghost and fire.

17 Whose fan in his hand/Whose winnowing tool is in his hand, and he shall purge his floor of corn [and he shall purge his corn floor], and shall gather the wheat into his barn; but the chaff he shall burn with fire unquenchable.

18 And many other things also he spake, and preached to the people. [Forsooth and he stirring, or admonishing, many other things, evangelized to the people.]
