1 Corinthians 2

12 Now we have received, not the Spirit [Ruach] of the world, but the Spirit [Ruach] which is of God-The Father; that we might know the things that are freely given to us of God-The Father.

13 Which things also we speak, not in the words which man’s wisdom teaches, but which the Holy Spirit [Ruach HaKodesh] teaches; comparing spiritual things with spiritual.

14 But the natural man receives not the things of the Spirit [Ruach] of God-The Father: for they are foolishness unto him: neither can he know [them], because they are spiritually discerned.
