Deuteronomy 21:16
Clementine Vulgate · Berean Standard Bible
volueritque substantiam inter filios suos dividere, non poterit filium dilectæ facere primogenitum, et præferre filio odiosæ :
when that man assigns his inheritance to his sons he must not appoint the son of the beloved wife as the firstborn over the son of the unloved wife.
