The word(s) "cave" appears 13 time(s) in 10 verse(s) in Quran in Mohsin Khan translation.

(1) If you help him (Muhammad صلى الله عليه وسلم) not (it does not matter), for Allah did indeed help him when the disbelievers drove him out, the second of the two; when they (Muhammad صلى الله عليه وسلم and Abu Bakr رضي الله عنه) were in the cave, he (صلى الله عليه وسلم) said to his companion (Abu Bakr رضي الله عنه): "Be not sad (or afraid), surely Allah is with us." Then Allah sent down His Sakinah (calmness, tranquillity, peace) upon him, and strengthened him with forces (angels) which you saw not, and made the word of those who disbelieved the lowermost, while the Word of Allah that became the uppermost; and Allah is All-Mighty, All-Wise.

(2) Should they find a refuge, or caves, or a place of concealment, they would turn straightway thereto with a swift rush.

(3) Do you think that the people of the cave and the Inscription (the news or the names of the people of the cave) were a wonder among Our Signs?

(4) (Remember) when the young men fled for refuge (from their disbelieving folk) to the cave. They said: "Our Lord! Bestow on us mercy from Yourself, and facilitate for us our affair in the right way!"

(5) Therefore We covered up their (sense of) hearing (causing them to go in deep sleep) in the cave for a number of years.

(6) (The young men said to one another): "And when you withdraw from them, and that which they worship, except Allah, then seek refuge in the cave; your Lord will open a way for you from His Mercy and will make easy for you your affair (i.e. will give you what you will need of provision, dwelling)."

(7) And you might have seen the sun, when it rose, declining to the right from their cave, and when it set, turning away from them to the left, while they lay in the midst of the cave. That is (one) of the Ayat (proofs, evidence, signs) of Allah. He whom Allah guides, he is the rightly guided; but he whom He sends astray, for him you will find no Wali (guiding friend) to lead him (to the right Path).

(8) And you would have thought them awake, whereas they were asleep. And We turned them on their right and on their left sides, and their dog stretching forth his two forelegs at the entrance [of the cave or in the space near to the entrance of the cave (as a guard at the gate)]. Had you looked at them, you would certainly have turned back from them in flight, and would certainly have been filled with awe of them.

(9) (Some) say they were three, the dog being the fourth among them; and (others) say they were five, the dog being the sixth, - guessing at the unseen; (yet others) say they were seven, and the dog being the eighth. Say (O Muhammad صلى الله عليه وسلم): "My Lord knows best their number; none knows them but a few." So debate not (about their number) except with the clear proof (which We have revealed to you). And consult not any of them (people of the Scripture - Jews and Christians) about (the affair of) the people of the cave.

(10) And they stayed in their cave three hundred (solar) years, adding nine (for lunar years). (Tafsir Al-Qurtubi)
