'Accomplished' in the Bible

It shall happen, when seventy years are accomplished, that I will punish the king of Babylon, and that nation, says Yahweh, for their iniquity, and the land of the Chaldeans; and I will make it desolate forever.

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.

Go, and speak to Ebedmelech the Ethiopian, saying, Thus says Yahweh of Armies, the God of Israel: Behold, I will bring my words on this city for evil, and not for good; and they shall be accomplished before you in that day.
