Albert Barnes Commentary Proverbs 10:29

"The way of Jehovah is a stronghold to the upright; But it is a destruction to the workers of iniquity." — Proverbs 10:29 (ASV)

Omit "shall be." The meaning is: The Way of Yahweh, i.e., the Divine Order of the world, has its two sides. It is strength to the upright, destruction to the workers of iniquity.
