'Man's' in the Bible

And he took hold of the blind man's hand [and] led him outside the village, and [after] spitting in his eyes, he placed his hands on him [and] asked him, "Do you see anything?"

And the Spirit told me to accompany them, not hesitating [at all]. So these six brothers also went with me, and we entered into the man's house.

And the first living creature [was] similar to a lion, and the second living creature [was] similar to an ox, and the third living creature had a face like a man's, and the fourth living creature [was] similar to an eagle flying.

Here is wisdom: the one who has understanding, let him calculate the number of the beast, for it is man's number, and his number [is] six hundred sixty-six.
