'Perform' in the Bible
Then Yahweh said to me, "You have seen well; for I watch over my word to perform it."
even the prophet Jeremiah said, Amen: Yahweh do so; Yahweh perform your words which you have prophesied, to bring again the vessels of Yahweh's house, and all them of the captivity, from Babylon to this place.
For thus says Yahweh, 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, says Yahweh, 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 to the queen of the sky, and to pour out drink offerings to 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 food, and were well, and saw no evil.
Thus says Yahweh of Armies, the God of Israel, saying, You 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 the sky, and to pour out drink offerings to her: establish then your vows, and perform your vows.
