Parallel
Matthew 5:13
Clementine Vulgate · Berean Standard Bible
Vos estis sal terræ. Quod si sal evanuerit, in quo salietur ? ad nihilum valet ultra, nisi ut mittatur foras, et conculcetur ab hominibus.
You are the salt of the earth. But if the salt loses its savor, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled by men.
