'Knew' in the Bible

Stealing, murdering, and committing adultery, And swearing to falsehood, and giving perfume to Baal, And going after other gods whom ye knew not.

And I have scattered them among nations Which they knew not, they and their fathers, And have sent after them the sword, Till I have consumed them.

If I have gone forth to the field, Then, lo, the pierced of the sword! And if I have entered the city, Then, lo, the diseased of famine! For both prophet and priest have gone up and down Unto a land that they knew not.

because that they have forsaken Me, and make known this place, and make perfume in it to other gods, that they knew not, they and their fathers, and the kings of Judah, and they have filled this place with innocent blood,

A grief -- a despised broken thing -- is this man Coniah? A vessel in which there is no pleasure? Wherefore have they been cast up and down, He and his seed, Yea, they were cast on to a land that they knew not?

because of their wickedness that they have done, by provoking Me to anger, by going to make perfume, by serving other gods, that they knew not, they, ye, and your fathers.
