'Man' in the Bible

when he nullified in his flesh the law of commandments in decrees. He did this to create in himself one new man out of two, thus making peace,

You were taught with reference to your former way of life to lay aside the old man who is being corrupted in accordance with deceitful desires,

and to put on the new man who has been created in God's image -- in righteousness and holiness that comes from truth.

For this reason a man will leave his father and mother and will be joined to his wife, and the two will become one flesh.
