'Produce' denotes fruit derived from the good of charity, and truth of faith.

(References: Arcana Coelestia 6108, 6155, Genesis 47:24)

6155. 'And so it will be at ingatherings' means the fruits from this. This is clear from the meaning of 'ingatherings' as the fruits, for the harvest which comes forth from the field is the fruits of that field.
