OET interlinear YHN (JHN) 18:11

uW Translation Notes:

Note 1 topic: figures-of-speech / rquestion

τὸ ποτήριον ὃ δέδωκέν μοι ὁ Πατὴρ, οὐ μὴ πίω αὐτό?

(Some words not found in SR-GNT: εἶπεν Οὖν ὁ Ἰησοῦς τῷ Πέτρῳ Βάλε τήν μάχαιραν εἰς τήν θήκην τό ποτήριον ὅ δέδωκεν μοί ὁ Πατήρ οὒ μή πίω αὐτό)

Jesus is using the form of a question to add emphasis to his statement. If you would not use a rhetorical question for this purpose in your language, you could translate his words as a statement or an exclamation and communicate the emphasis in another way. Alternate translation: [I should certainly drink the cup that the Father has given to me!]

Note 2 topic: figures-of-speech / metaphor

τὸ ποτήριον ὃ δέδωκέν μοι ὁ Πατὴρ, οὐ μὴ πίω αὐτό

(Some words not found in SR-GNT: εἶπεν Οὖν ὁ Ἰησοῦς τῷ Πέτρῳ Βάλε τήν μάχαιραν εἰς τήν θήκην τό ποτήριον ὅ δέδωκεν μοί ὁ Πατήρ οὒ μή πίω αὐτό)

Here Jesus uses cup to refer to the sufferings he will soon experience as if they were a cup of bitter-tasting liquid that God would give him to drink. If this use of cup and drink would confuse your readers, you could express the meaning explicitly. Alternate translation: [My suffering which the Father wants me to endure, should I certainly not endure it]

Father is an important title for God.
