'Portion' in the Bible

When all Israel saw that the king refused to listen to them, the people answered the king, "We have no portion in David -- no share in the son of Jesse! Return to your homes, O Israel! Now, look after your own dynasty, O David!" So all Israel returned to their homes.

He ordered the people living in Jerusalem to contribute the portion prescribed for the priests and Levites so they might be obedient to the law of the Lord.

When the edict was issued, the Israelites freely contributed the initial portion of their grain, wine, olive oil, honey, and all the produce of their fields. They brought a tenth of everything, which added up to a huge amount.
