Deuteronomy 21:16-17

16then on the day when ahe assigns his possessions as an inheritance to his sons, he may not treat the son of the loved as the firstborn in preference to the son of the unloved, who is the firstborn, 17but he shall acknowledge the firstborn, the son of the unloved, by giving him a double portion of all that he has, for he is bthe firstfruits of his strength. cThe right of the firstborn is his.

Psalms 16:5-6

5 The Lord is dmy chosen portion and my ecup;
you hold my flot.
6 gThe lines have fallen for me in pleasant places;
indeed, I have a beautiful inheritance.

Psalms 17:14

14from men by your hand, O Lord,
from hmen of the world whose iportion is in this life.
Or  from men whose portion in life is of the world

You fill their womb with treasure;
Or As for your treasured ones, you fill their womb

they are satisfied with lchildren,
and they leave their abundance to their infants.
