1 Corinthians 2:10 in the King James Version
But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
Context
9 But as it is written, “Things which an eye didn’t see, and an ear didn’t hear, which didn’t enter into the heart of man, these God has prepared for those who love him.”
10 But to us, God revealed them through the Spirit. For the Spirit searches all things, yes, the deep things of God.
11 For who among men knows the things of a man except the spirit of the man which is in him? Even so, no one knows the things of God except God’s Spirit.
