Between Germany’s Erntedank and America’s Thanksgiving there are plenty of harvest festivals around the world.
Psalm 65 is a great song for the occasion:
10 You send abundant rain on the plowed fields and soak them with water; you soften the soil with showers and cause the young plants to grow.
11 What a rich harvest your goodness provides! Wherever you go there is plenty.
12 The pastures are filled with flocks; the hillsides are full of joy.
13 The fields are covered with sheep; the valleys are full of wheat. Everything shouts and sings for joy.
