OET interlinear YHN (JHN) 1:33

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

κἀγὼ οὐκ ᾔδειν αὐτόν

and_I not /had/_known him

Here John means that he did not know previously that Jesus was the Messiah. It does not mean that he didn’t recognize who Jesus was when he saw him. If it would be helpful in your language, you could state this explicitly. Alternate translation: “And I did not recognize that he was the Messiah”

Note 2 topic: figures-of-speech / explicit

ὁ πέμψας με βαπτίζειν ἐν ὕδατι, ἐκεῖνός

the_‹one› /having/_sent me /to_be/_baptizing in water that_‹one›

Here, the phrases the one who sent me and that one both refer to God. If this might confuse your readers, you could express the meaning explicitly. Alternate translation: “God, who sent me to baptize in water,”

Note 3 topic: figures-of-speech / metaphor

οὗτός ἐστιν ὁ βαπτίζων ἐν Πνεύματι Ἁγίῳ

he is the_‹one› baptizing in /the/_Spirit Holy

Here John the Baptist is using literal baptism, which puts a person under water, to refer to spiritual baptism, which puts people under the influence of the Holy Spirit, who purifies them. If this might confuse your readers, you could express the meaning plainly. Alternate translation: “he is the one who will put you under the influence of the Holy Spirit, who will purify you”
