'Portion' in the Bible

Instead he shall acknowledge the son of the unloved as the firstborn, by giving him a double portion of all that he has, for he was the beginning of his strength (generative power); to him belongs the right of the firstborn.

“For the Lord’s portion and chosen share is His people;Jacob (Israel) is the allotment of His inheritance.

“He selected the best [land] for himself,For there the leader’s portion was reserved;Yet he came with the leaders of the people;He carried out the justice (righteous will) of the Lord,And His ordinances (judgments) with Israel.”
