1 Corinthians 2:9-11

Young's Literal Translation

⁹ but, according as it hath been written, `What eye did not see, and ear did not hear, and upon the heart of man came not up, what God did prepare for those loving Him --'

¹⁰ but to us did God reveal [them] through His Spirit, for the Spirit all things doth search, even the depths of God,

¹¹ for who of men hath known the things of the man, except the spirit of the man that [is] in him? so also the things of God no one hath known, except the Spirit of God.
