'Known' in the Bible

Only you I have known of all families of the land, Therefore I charge on you all your iniquities.

And they have not known to act straightforwardly, An affirmation of Jehovah, Who are treasuring up violence and spoil in their palaces.

For I have known -- many are your transgressions, And mighty your sins, Adversaries of the righteous, taking ransoms, And the needy in the gate ye turned aside.
