'Man's' in the Bible

Which things also we speak, not in words which man's wisdom teaches, but which the Holy Spirit teaches, comparing spiritual things with spiritual things.

each man's work will be revealed. For the Day will declare it, because it is revealed in fire; and the fire itself will test what sort of work each man's work is.

If any man's work remains which he built on it, he will receive a reward.

If any man's work is burned, he will suffer loss, but he himself will be saved, but as through fire.

But with me it is a very small thing that I should be judged by you, or by man's judgment. Yes, I don't judge my own self.
