Surah 2:253
"Those are the messengers – We have favored some of them over others. (There were) some of them to whom God spoke, and some of them He raised in rank. And We gave Jesus, son of Mary, the clear signs, and supported him with the holy spirit. If God had (so) pleased, those who (came) after them would not have fought each other, after the clear signs had come to them. But they differed, and (there were) some of them who believed and some of them who disbelieved. If God had (so) pleased, they would not have fought each other. But God does whatever He wills."
2.253 – And We gave Jesus, son of Mary, the clear signs, and supported him with the holy spirit.
For the second time in this sūra, the Quran describes ‘Īsā as supported by the holy spirit. See the comments on the name ‘Īsā at 2.87 and on the holy spirit at 16.102.
On the disagreement and in-fighting of those who “followed after them,” see the comments at 98.4.
