Isaías 54:16,17

No weapon formed against Zion shall prosper, because both the makers of weapons and those who use them are alike created by Jehovah, and all their activity is under His control.

the smith that bloweth the fire of coals (R.V.)] Cf. ch. Isaías 44:12.

an instrument for his work rather for its work, or perhaps "according to its work," adapted to the particular work for which it is intended, a scythe for reaping, a sword for slaughter, and so on. The smith will turn out anything, amongst other things deadly weapons, but all by the permission of Jehovah who has made him.

the waster to destroy Not "to destroy the weapon that the smith has made"; the "waster" is the one for whose use the weapon is made; he also is the creature of Jehovah.
