You will seek them but will not find them. Those who wage war against you will come to nothing.
KJV
Thou shalt seek them, and shalt not find them, [even] them that contended with thee: they that war against thee shall be as nothing, and as a thing of nought.
ASV
Thou shalt seek them, and shalt not find them, even them that contend with thee: they that war against thee shall be as nothing, and as a thing of nought.
