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

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

'Look not back behind thee,' as in Genesis 19:17, means that Lot, who represents the good of charity, should not look to matters of doctrine. 'To look up,' is to look to celestial things. In Genesis 18:22, looking signifies thinking because seeing denotes understanding.
