The Women - 4:155
"Allah sealed their understanding because of their breaking their word, because they disbelieved in the signs and proofs of Allah, because they killed the prophets unjustly, and because they said: "We are fixed-minded", yes, because of their disbelief. Therefore few of them believe."
Why did the Children of Israel kill the prophets?
The Table Spread/5:70
We took a promise from the Children of Israel and sent messengers to them. Whenever a messenger came to them with something they did not like, they denied some of them and killed some of them.
The Cow/2:87
We gave Moses the Book and sent messengers after him in succession. And We gave clear proofs to Jesus, son of Mary, and We supported him with the Holy Spirit. Whenever a messenger came to you with something you did not like, were you not arrogant? Indeed, some of them you denied and some of them you killed.
