read this :
I passed by and saw you kicking about in your blood, and as you lay there in your blood I said to you, ‘Live!’ I made you grow like a plant of the field. You grew up and developed and became the most beautiful of jewels. Your breasts were formed and your hair grew, you who were naked and bare. Later I passed by, and when I looked at you and saw that you were old enough for love, I spread the corner of my garment over you and covered your nakedness.
commentary by a Jewish source:
God wills the abandoned infant to live. She lives and grows to puberty… Upon reaching puberty, she is ready for marriage… (The Jewish Study Bible: Tanakh Translation, Torah, Nevi’im, Kethuvim p.1069)
this is Christian:
It is not only fornication, but also the giving in marriage prematurely, that is called fornication; when, so to speak, one not of ripe age is given to a husband, either of her own accord or by her parents. (Clement of Alexandria, IX.-Fragment of the Treatise on Marriage, Early Church Fathers - Ante-Nicene Fathers, Volume II;
“The wife was to be taken from within the larger family circle (usually at the ‘outset of puberty’ or around the age of 13) in order to maintain the purity of the family line.”
