This, from the BCP, and in The Divine Hours today:
Almighty and gracious Father, we give you thanks for the fruits of the earth in their season and for the labors of those who harvest them. Make us, we pray, faithful stewards of your great bounty, for the provision of our necessities and the relief of all who are in need, to the glory of your Name; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God now and for ever. Amen.
