An-Nisaa 4:155

[They were cursed] for breaking their covenant, rejecting the signs of Allah, killing the prophets unjustly, and for their saying, “Our hearts are wrapped up”. Rather, it is Allah Who has sealed them for their disbelief; so none of them will believe except a few –

And [We cursed them][230] for their breaking of the covenant and their disbelief in the signs of Allāh and their killing of the prophets without right and their saying, "Our hearts are wrapped" [i.e., sealed against reception]. Rather, Allāh has sealed them because of their disbelief, so they believe not, except for a few.[231]

[230] Another interpretation is "And [We made certain good foods unlawful to them]," based upon verse 160.
[231] Or "except with little belief."

155. Because of their breaking the covenant, and of their rejecting the Ayât (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allâh, and of their killing the Prophets unjustly, and of their saying: "Our hearts are wrapped (with coverings, i.e. we do not understand what the Messengers say)" - nay, Allâh has set a seal upon their hearts because of their disbelief, so they believe not but a little.

Then because of their breaking of their covenant, and their disbelieving in the revelations of Allah, and their slaying of the prophets wrongfully, and their saying: Our hearts are hardened - Nay, but Allah set a seal upon them for their disbelief, so that they believe not save a few -
