As I have mentioned before, Jesus isn't directly quoted saying "I am the son of God" himself, rather others are quoted both (1) referring to Jesus as the son of God and (2) referring to times when they had heard Jesus address himself in this way.

But when you phrased it as "which Bible" rather than which verse, such a comment shows a spirit which, as it comes across to me, does not wish to actually be educated or gain anything from being in conversation with others. It strikes me as only wanting to preach at others.

However, in case I am mistaken and it was a sincere question, the answer is you can find verses which refer to Jesus as "the son of God" in every English version ever produced, as "el hijo de Dios" in every Spanish version, as "hyios tou theou" in every Greek copy of the New Testament. I've already provided a link to them above, but repeat it here in case you missed it: verses in which the phrase "son of God" is used, most (not all) of them referring to Jesus.
