1 Corinthians 16:2

Upon the first day of the week; the day set apart and observed by the apostles and Christians as the Lord's day, the Christian Sabbath.

Lay by him in store; at home.

That there be no gatherings; that their gifts might be ready when the apostle should come. As the first day of the week is the Lord's day, and from his resurrection has been observed by his people as sacred to his worship, it is a proper time for them to consider his goodness, and contribute, or lay by in store, as he has prospered them, for the supply of the wants of their fellow-men.
