The word(s) "confirming" appears 17 time(s) in 16 verse(s) in Quran in Muhammad Pickthal translation.

(11) And unto thee have We revealed the Scripture with the truth, confirming whatever Scripture was before it, and a watcher over it. So judge between them by that which Allah hath revealed, and follow not their desires away from the truth which hath come unto thee. For each We have appointed a divine law and a traced-out way. Had Allah willed He could have made you one community. But that He may try you by that which He hath given you (He hath made you as ye are). So vie one with another in good works. Unto Allah ye will all return, and He will then inform you of that wherein ye differ.

I am the messenger of Allah unto you, confirming that which was (revealed) before me in the Torah, and bringing good tidings of a messenger who cometh after me, whose name is the Praised One. Yet when he hath come unto them with clear proofs, they say: This is mere magic.
