Genesis 11:30

Hebrew וָלָֽד walad. Masculine singular. This is the only instance of this word walad (boy, offspring Strong’s #3206) in the Masoretic Text. It is also found in 2 Sam 6:23, according to Gesenius, with the same phrasing but also the masculine verb to be, though other translations ignore the gender:

“Michal, built-one of Saul, a boy has not become to her until the hot-one of her death.”

This phrase specifically speaks to possession and lacks any verbiage about bearing as is usual when speaking about mothers giving birth, i.e. “she conceives and bears Cain” Genesis 4:1. Jesus said every stroke and tittle of the Law matters. “Has become” is indicative of the predestined, those chosen from the foundation of the world to become heirs, the ones “from-to the Age.”
