Êxodo 13:2
Therefore let us draw together from the divine Scriptures instances in which we find "holy" used, and discover not only persons but also mute animals that are called "holy," and also find both "the vessels" of the ministry that are called "holy," and the garments which are said to be "holy," and even the places which were located in cities and suburbs and counted as priestly. Indeed, among the brute animals it is commanded through the law that "the firstborn" of calves or cattle be sacrificed to the Lord, and it says, You will not do any work with them because they have been consecrated to the Lord. — HOMILIES ON LEVITICUS 11.1.2
Êxodo 13:2
Males were sacred because they opened their mothers' wombs. They were offered before the altar of the Lord. Scripture says, "Every male that opens the womb.…" This phrase has a spiritual meaning. For you might say that "every male is brought forth from the womb" but does not open the womb of his mother in the way that the Lord Jesus did. In the case of every other woman, it is not the birth of an infant but intercourse with a man that opens the womb. But the womb of the Lord's mother was opened at the time when her offspring was brought forth, because before the birth of Christ a male did not even touch her womb, holy as it was and deserving of all respect. — HOMILIES ON THE GOSPEL OF LUKE 14:7-8
