Isaiah55:11

Translation

My word that goes out from my mouth shall be thus, it shall not return to me empty but will accomplish what I desire and it will succeed [in that] for which I sent it.

Paraphrase

Any word that I speak will act in this way: it will not bounce back to me like an unfruitful echo, rather it will do what I want it to do and succeed in the purpose for which I sent it.
