Sirach 35:13LXX

11In every gift shew a cheerful countenance, and sanctify thy tithes with joy.

12Give to the most High according to what he hath given to thee, and with a good eye do according to the ability of thy hands:

13For the Lord maketh recompense, and will give thee seven times as much.

14Do not offer wicked gifts, for such he will not receive.

15And look not upon an unjust sacrifice, for the Lord is judge, and there is not with him respect of person.
