John the Apostle
John 3:8BSB·traditional attribution

The wind blows where it wishes. You hear its sound, but you do not know where it comes from or where it is going. So it is with everyone born of the Spirit.”

John Calvin Reformed @genevareformer

8. The wind bloweth where it pleaseth. Not that, strictly speaking, there is will in the blowing, but because the agitation is free, and uncertain, and variable; for the air is carried sometimes in one direction and sometimes in another. How this applies to the case in hand; for if it flowed in a uniform motion like water, it would be less miraculous.

Matthew Henry Presbyterian @wholebiblehenry

We found, in the close of the foregoing chapter, that few were brought to Christ at Jerusalem; yet here was one, a considerable one. It is worth while to go a great way for the salvation though but of one soul. Observe, I. Who this Nicodemus was. Not many mighty and noble are called; yet some are, and here was one.
