While the sun, or the light, or the moon, or the stars, be not darkened, nor the clouds return after the rain: While the sun, or the light, or the moon, or the stars, be not darkened - i.e., in the Spring, prime, and prosperity of life.
Nor the clouds return - The infirmities of old age of which Winter is a proper emblem, as spring is of youth, in the former clause of this verse.
