OET interlinear YHN (JHN) 9:33

uW Translation Notes:

Note 1 topic: figures-of-speech / doublenegatives

εἰ μὴ ἦν οὗτος παρὰ Θεοῦ, οὐκ ἠδύνατο ποιεῖν οὐδέν

except ¬not/lest was this_‹man› from God not ˱he˲_/was/_able /to_be/_doing nothing

Here, the formerly blind man uses a double negative sentence pattern to emphasize the positive fact that Jesus must be from God. If this double-negative pattern would be misunderstood in your language, you could translate it as a positive statement. Alternate translation: “Only a man from God would be able to do anything like that!”

Note 2 topic: grammar-connect-condition-contrary

εἰ μὴ ἦν οὗτος παρὰ Θεοῦ

except ¬not/lest was this_‹man› from God

The formerly blind man is making a conditional statement that sounds hypothetical, but he is already convinced that the condition is not true. He has concluded that Jesus must have come from God because he healed him. Use a natural form in your language for introducing a condition that the speaker believes is not true. Alternate translation: “If this one were not from God, but he is”

Note 3 topic: figures-of-speech / explicit

μὴ ἦν & παρὰ Θεοῦ

¬not/lest was & from God

See how you translated from God in 9:16. Alternate translation: “did not have God’s authority”

Note 4 topic: figures-of-speech / explicit

οὐδέν

nothing

Here, anything does not mean “anything at all.” It means anything like the miraculous signs that Jesus was performing, particularly his healing of this man who was born blind. If this might confuse your readers, you could express the meaning explicitly. Alternate translation: “anything like healing a man blind from birth”
