'Ignorance' in the Bible

“But if they do not hear and obey, they will die by the sword [of God’s destructive judgments]And they will die [in ignorance] without [true] knowledge.

With all my heart I have sought You, [inquiring of You and longing for You];Do not let me wander from Your commandments [neither through ignorance nor by willful disobedience].

If you [claim ignorance and] say, “See, we did not know this,”Does He not consider it who weighs and examines the hearts and their motives?And does He not know it who guards your life and keeps your soul?And will He not repay [you and] every man according to his works?

You shall do this on the seventh [day] of the month for everyone who goes astray [and sins through error or ignorance] and for him who is naive; so shall you make atonement for the temple (house).
