Verse 4

إِن تَتُوبَآ إِلَى ٱللَّهِ فَقَدْ صَغَتْ قُلُوبُكُمَا وَإِن تَظَـٰهَرَا عَلَيْهِ فَإِنَّ ٱللَّهَ هُوَ مَوْلَىٰهُ وَجِبْرِيلُ وَصَـٰلِحُ ٱلْمُؤْمِنِينَ وَٱلْمَلَـٰٓئِكَةُ بَعْدَ ذَٰلِكَ ظَهِيرٌ

If you both repent to God, then indeed your hearts have listened. But if you support each other against him, then surely God is his supporter, and so is Gabriel, and the righteous faithful and the angels also will protect him.
