'Performed' in the Bible

For I am Jehovah; I will speak, and the word that I shall speak shall be performed; it shall be no more deferred: for in your days, O rebellious house, will I speak the word, and will perform it, saith the Lord Jehovah.

Therefore say unto them, Thus saith the Lord Jehovah: There shall none of my words be deferred any more, but the word which I shall speak shall be performed, saith the Lord Jehovah.

And I will put my Spirit in you, and ye shall live, and I will place you in your own land: and ye shall know that I, Jehovah, have spoken it and performed it, saith Jehovah.
