'Man's' in the Bible

It was as thick as a man's open hand, and the edge of it was curved like the edge of a cup, like a lily flower; it would take three thousand baths.

And Asa made prayer to the Lord his God and said, Lord, you only are able to give help against the strong to him who has no strength; come to our help, O Lord our God, for our hope is in you, and in your name we have come out against this great army. O Lord, you are our God; let not man's power be greater than yours.
