Jerome : (Verse 15) The remaining five thousand cubits in width, along the twenty-five thousand, shall be for common use by the city for dwellings and common land, and the city shall be in the middle of it. What we translate as 'profane', Aquila translated as 'βέβηλον', Symmachus and Theodotion translated as 'λαἳκὸν'; the LXX used 'προτείχισμα' which can also be translated as 'antemurale'. 'Profane' and 'laicum' are both secular, that is, common, and can be used by all people everywhere. However, the remaining five thousand in width, by twenty-five thousand, is understood to be the length, will be profane of the city: so that it is lawful for all the Israelites and every member of the people to dwell there; not because they are unclean or because anything in the habitation of the holy land is contaminated, putrid, and filthy; but because, apart from the priests, it is permitted for everyone to dwell in them. By this we understand that all the things we refer to as sensations, that is, bodily pleasures that we perceive by sight, hearing, touch, smell, and taste, are profane and do not have the sanctity of the temple, nor do they have the privilege of the priesthood, but rather they belong to the realm of the laity and commoners. However, the city will be in the middle, concerning which it is written: The stream of the river makes the city of God glad (Ps. 46:4). And: A city set on a hill cannot be hidden (Matthew 5:14): of which we will speak in the following. Προτείχισμα, which means a fortification, and διάστημα, which means a space, which the LXX translated as suburbs, we do not know the meaning they have in this place. — Commentary on Ezekiel
