'Man's' in the Bible

"They say, 'If a man puts away his wife, and she goes from him, and become another man's, will he return to her again?' Wouldn't that land be greatly polluted? But you have played the prostitute with many lovers; yet return again to me," says Yahweh.

You shall mention the burden of Yahweh no more: for every man's own word shall be his burden; for you have perverted the words of the living God, of Yahweh of Armies our God.
