'Knowledge' in the Bible

“And it will not be [necessary] for each one to teach his fellow citizen,Or each one his brother, saying, ‘Know [by experience, have knowledge of] the Lord,’For all will know [Me by experience and have knowledge of] Me,From the least to the greatest of them.

For if we go on willfully and deliberately sinning after receiving the knowledge of the truth, there no longer remains a sacrifice [to atone] for our sins [that is, no further offering to anticipate],

For you showed sympathy and deep concern for those who were imprisoned, and you joyfully accepted the [unjust] seizure of your belongings and the confiscation of your property, conscious of the fact that you have a better possession and a lasting one [prepared for you in heaven].
