Passages that are always read at the feasts of the Virgin Mary

At the all-night service of all the Mother of God holidays, three passages from the Old Testament are read. Each time, as well as the Gospel reading, the same passages are read regardless of which particular feast of the Virgin Mary is celebrated.

The first three passages are from Genesis chapter 28 verses 11-17;
the second three passages are from the book of the prophet Ezekiel, chapter 43, verse 27, chapter 44, verses 1-4:
the third three passages are from the book of the Wisdom of King Solomon, chapter 9, verses 1-11.

Each of these passages prophesies of the Virgin Mary. According to the interpretation of the Holy Fathers, the Virgin Mary appears in these passages either through the prototype of the ladder, which Jacob saw in a dream (the first three passages), then through the prototype of the closed gates (second three passages), then through the prototype of the House that Wisdom created (the third three passages).
