In Leviticus, the length of purification time after the birth of a daughter is twice the length of the time for a son. This is generally cited as proof that the Bible is anti-woman. Having come to spend much more time in my life around birthing mothers, I see something that was always there if I could have but opened my world-blinded eyes.
The extra time for a daughter is extra bonding time and extra time for the husband as well. Given the inheritance rules, if the times of “no-touch wifey” were the same, there would be temptation to rush things after the birth of daughters in a pursuit of sons. But by enforcing a longer time of purification (and correspondingly time to physically recover and bond with the baby and enjoy that old oxytocin song) for daughters, this temptation is subverted and husbands have extra time to value their daughters and give their wives the reassurance of their faithfulness by abstaining for even longer than with a son. It also, with the extra bonding time, provides a means for the very earliest sort of woman-to-woman support to happen. Thus, what looks like oppression is actually a way to establish that daughters are precious and to be valued despite the fact that their place and future follows a different path than that of sons. Both different, but both precious and worthy of love.
