(Maryam) 19 : 17
فَاتَّخَذَتْ مِنْ دُونِهِمْ حِجَابًا فَأَرْسَلْنَا إِلَيْهَا رُوحَنَا فَتَمَثَّلَ لَهَا بَشَرًا سَوِيًّا
And she placed a screen from them; then We sent to her Our Spirit, and he represented himself to her as a well-proportioned man.
Spirit mentioned in this verse is Angel Jibreel. Just like everyone, the Spirit of Jesus is also of Lord as explained in verse 4: 171. See explanation 16: 102.
