The word(s) "israel" appears 43 time(s) in 41 verse(s) in Quran in Muhammad Habib Shakir translation.

(41) O you who believe! be helpers (in the cause) of Allah, as~ Isa son of Marium said to (his) disciples: Who are my helpers in the cause of Allah? The disciples said: We are helpers (in the cause) of Allah. So a party of the children of israel believed and another party disbelieved; then We aided those who believed against their enemy, and they became uppermost.
