'Ignorance' in the Bible

You asked, “Who is this who conceals My counsel with ignorance?”Surely I spoke about things I did not understand,things too wonderful for me to know.

“How long, foolish ones, will you love ignorance?How long will you mockers enjoy mockingand you fools hate knowledge?

You must do the same thing on the seventh day of the month for everyone who sins unintentionally or through ignorance. In this way you will make atonement for the temple.
