The word(s) "keep" appears 36 time(s) in 34 verse(s) in Quran in Saheeh International translation.

(1) And [recall] when We saved your forefathers from the people of Pharaoh, who afflicted you with the worst torment, slaughtering your [newborn] sons and keeping your females alive. And in that was a great trial from your Lord.

(2) And they ask you about menstruation. Say, "It is harm, so keep away from wives during menstruation. And do not approach them until they are pure. And when they have purified themselves, then come to them from where Allah has ordained for you. Indeed, Allah loves those who are constantly repentant and loves those who purify themselves."

(3) Divorce is twice. Then, either keep [her] in an acceptable manner or release [her] with good treatment. And it is not lawful for you to take anything of what you have given them unless both fear that they will not be able to keep [within] the limits of Allah. But if you fear that they will not keep [within] the limits of Allah, then there is no blame upon either of them concerning that by which she ransoms herself. These are the limits of Allah, so do not transgress them. And whoever transgresses the limits of Allah - it is those who are the wrongdoers.

(4) And if he has divorced her [for the third time], then she is not lawful to him afterward until [after] she marries a husband other than him. And if the latter husband divorces her [or dies], there is no blame upon the woman and her former husband for returning to each other if they think that they can keep [within] the limits of Allah. These are the limits of Allah, which He makes clear to a people who know.

(5) And when you divorce women and they have [nearly] fulfilled their term, either retain them according to acceptable terms or release them according to acceptable terms, and do not keep them, intending harm, to transgress [against them]. And whoever does that has certainly wronged himself. And do not take the verses of Allah in jest. And remember the favor of Allah upon you and what has been revealed to you of the Book and wisdom by which He instructs you. And fear Allah and know that Allah is Knowing of all things.

(6) O you who have believed, do not invalidate your charities with reminders or injury as does one who spends his wealth [only] to be seen by the people and does not believe in Allah and the Last Day. His example is like that of a [large] smooth stone upon which is dust and is hit by a downpour that leaves it bare. They are unable [to keep] anything of what they have earned. And Allah does not guide the disbelieving people.

(7) Whoever intercedes for a good cause will have a reward therefrom; and whoever intercedes for an evil cause will have a burden therefrom. And ever is Allah, over all things, a keeper.

(8) But the answer of his people was only that they said, "Evict them from your city! Indeed, they are men who keep themselves pure."

(9) And the eminent among the people of Pharaoh said," Will you leave Moses and his people to cause corruption in the land and abandon you and your gods?" [Pharaoh] said, "We will kill their sons and keep their women alive; and indeed, we are subjugators over them."

(10) And [recall, O Children of Israel], when We saved you from the people of Pharaoh, [who were] afflicting you with the worst torment - killing your sons and keeping your women alive. And in that was a great trial from your Lord.
