Sirach 35:6-10
The just man’s sacrifice is most pleasing, nor will it be forgotten. In generous spirit pay homage to the Lord, be not sparing of freewill gifts. With each contribution show a cheerful countenance and pay your tithes in a spirit of joy. Give to the Most High as he has given to you, generously according to your means. For the Lord is one who always repays, and He will give back to you seven-fold.
