'Man's' in the Bible

And my speech and my preaching was not with enticing words of man's wisdom, but in demonstration of the Spirit and of power:

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

Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.

If any man's work abide which he hath built thereupon, he shall receive a reward.

If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.

But with me it is a very small thing that I should be judged of you, or of man's judgment: yea, I judge not mine own self.

Conscience, I say, not thine own, but of the other: for why is my liberty judged of another man's conscience?
