'Man's' in the Bible

You yourselves are our letter, whose writing is in our heart, open for every man's reading and knowledge;

And we have given up the secret things of shame, not walking in false ways, and not making use of the word of God with deceit; but by the revelation of what is true, as before God, we have the approval of every man's sense of right and wrong.

So that we may be able to go on and take the good news to countries still farther away than you are, and not take credit for another man's work in making things ready to our hand.
