'Knew' in the Bible

I will do so because these people have rejected me and have defiled this place. They have offered sacrifices in it to other gods which neither they nor their ancestors nor the kings of Judah knew anything about. They have filled it with the blood of innocent children.

On the day after Gedaliah had been murdered, before anyone even knew about it,

This happened because of the wickedness the people living there did. They made me angry by worshiping and offering sacrifice to other gods whom neither they nor you nor your ancestors previously knew.

I set a trap for you, Babylon; you were caught before you knew it. You fought against me. So you were found and captured.
