Sefer HaBahir 38

1Rabbi Amorai sat and expounded, "Why is it written, 'YHVH loves the gates of Zion more than all the [other] dwellings of Jacob' (Psalms 87:2)? 'The gates of Zion' - these are the openings of the world. There is no gate that is not an opening, as we say, 'Open for us the gates of compassion' (High Holiday Prayers). Thus, the Blessed Holy One said, 'I love the gates of Zion, when they are open.' Why? Because they are from the side of evil. But when Israel are good before The Place and fitting to be opened to good, the Blessed Holy One loves them ' more than the dwellings of Jacob.' All of them are peace - as is written, 'And Jacob was a simple man, sitting in tents' (Genesis 25:27)."
