1 Corinthians 13:11 in the King James Version
When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.
Context
10 but when that which is complete has come, then that which is partial will be done away with.
11 When I was a child, I spoke as a child, I felt as a child, I thought as a child. Now that I have become a man, I have put away childish things.
12 For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I will know fully, even as I was also fully known.
