The word(s) "children of israel" appears 50 time(s) in 49 verse(s) in Quran in Mohsin Khan translation.

(41) He ['Îsa (Jesus)] was not more than a slave. We granted Our Favour to him, and We made him an example for the children of israel (i.e. his creation without a father).

(42) Saying: "Deliver to me the slaves of Allah (i.e. the children of israel). Verily, I am to you a Messenger worthy of all trust.

(43) Thus (it was)! And We made other people inherit them (i.e. We made the children of israel to inherit the kingdom of Egypt).

(44) And indeed We saved the children of israel from the humiliating torment:

(45) And We chose them (the children of israel) above the 'Alamin (mankind and jinn) [during the time of Musa (Moses)] with knowledge,

(46) And indeed We gave the children of israel the Scripture, and the understanding of the Scripture and its laws, and the Prophethood; and provided them with good things, and preferred them above the 'Alamin (mankind and jinn of their time, during that period),

(47) Say: "Tell me! If this (Qur'an) is from Allah and you deny it, and a witness from among the children of israel ('Abdullah bin Salam رضي الله عنه) testifies that [this Qur'an is from Allah (like the Taurat (Torah)], and he believed (embraced Islam) while you are too proud (to believe)." Verily, Allah guides not the people who are Zalimun (polytheists, disbelievers and wrong-doers).

(48) And (remember) when 'Îsa (Jesus), son of Maryam (Mary), said: "O children of israel! I am the Messenger of Allah unto you, confirming the Taurat [(Torah) which came] before me, and giving glad tidings of a Messenger to come after me, whose name shall be Ahmad. But when he (Ahmad i.e. Muhammad صلى الله عليه وسلم) came to them with clear proofs, they said: "This is plain magic."

(49) O you who believe! Be you helpers (in the Cause) of Allah as said 'Îsa (Jesus), son of Maryam (Mary), to the Hawariyyun (the disciples): "Who are my helpers (in the Cause) of Allah?" The Hawariyyun (the disciples) said: "We are Allah's helpers" (i.e. we will strive in His Cause!). Then a group of the children of israel believed and a group disbelieved. So We gave power to those who believed against their enemies, and they became the victorious (uppermost).
