The word(s) "concealing" appears 4 time(s) in 4 verse(s) in Quran in Saheeh International translation.

(1) And [recall] when you slew a man and disputed over it, but Allah was to bring out that which you were concealing.

(2) So you see those in whose hearts is disease hastening into [association with] them, saying, "We are afraid a misfortune may strike us." But perhaps Allah will bring conquest or a decision from Him, and they will become, over what they have been concealing within themselves, regretful.

(3) And when they come to you, they say, "We believe." But they have entered with disbelief [in their hearts], and they have certainly left with it. And Allah is most knowing of what they were concealing.

(4) And they did not appraise Allah with true appraisal when they said, "Allah did not reveal to a human being anything." Say, "Who revealed the Scripture that Moses brought as light and guidance to the people? You [Jews] make it into pages, disclosing [some of] it and concealing much. And you were taught that which you knew not - neither you nor your fathers." Say, "Allah [revealed it]." Then leave them in their [empty] discourse, amusing themselves.
