'Perform' in the Bible

Then said Jehovah unto me, Thou hast well seen: for I watch over my word to perform it.

even the prophet Jeremiah said, Amen: Jehovah do so; Jehovah perform thy words which thou hast prophesied, to bring again the vessels of Jehovah's house, and all them of the captivity, from Babylon unto this place.

For thus saith Jehovah, After seventy years are accomplished for Babylon, I will visit you, and perform my good word toward you, in causing you to return to this place.

Behold, the days come, saith Jehovah, that I will perform that good word which I have spoken concerning the house of Israel and concerning the house of Judah.

But we will certainly perform every word that is gone forth out of our mouth, to burn incense unto the queen of heaven, and to pour out drink-offerings unto her, as we have done, we and our fathers, our kings and our princes, in the cities of Judah, and in the streets of Jerusalem; for then had we plenty of victuals, and were well, and saw no evil.

Thus saith Jehovah of hosts, the God of Israel, saying, Ye and your wives have both spoken with your mouths, and with your hands have fulfilled it, saying, We will surely perform our vows that we have vowed, to burn incense to the queen of heaven, and to pour out drink-offerings unto her: establish then your vows, and perform your vows.
