Parallel
Isaiah 55:11
Brenton's English Septuagint · Berean Standard Bible
so shall my word be, whatever shall proceed out of my mouth, it shall by no means turn back, until all the things which I willed shall have been accomplished; and I will make thy ways prosperous, and [will effect] my commands.
so My word that proceeds from My mouth will not return to Me empty, but it will accomplish what I please, and it will prosper where I send it.
