OET interlinear YHN (JHN) 6:29

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

τοῦτό ἐστιν τὸ ἔργον τοῦ Θεοῦ, ἵνα πιστεύητε εἰς ὃν ἀπέστειλεν ἐκεῖνος

this is the work ¬the ˱of˲_God that ˱you_all˲_/may_be/_believing in whom sent_out that_‹one›

Here, Jesus says which work one must do in order to receive “the food that endures to eternal life” that was mentioned in verse 27. This work is not any kind of labor or deed that can be done, but it is faith in Jesus, which is a gift from God (Ephesians 2:8–9). If this might confuse your readers, you could express the meaning explicitly. Alternate translation: [This is the work of God that is required to receive the food that endures to eternal life: that you believe in the one whom that one has sent]

Note 3 topic: writing-pronouns

ἀπέστειλεν ἐκεῖνος

sent_out that_‹one›

Here, that one refers to God the Father. If it would be helpful in your language, you could state this explicitly. Alternate translation: [God has sent]
