Ezek 42:4

“"And before the treasury, there was a walkway ten cubits wide, looking inward, with the doors facing north." There was also before the treasury, or the halls, or the chambers, a walkway of ten cubits in width, looking towards the interior of the road of one cubit. And what was added by the Seventy: It is extra to have a length of one hundred cubits: for in the Hebrew it is not held, what they set forth, they took what is held in Hebrew, looking towards the interior of the road of one cubit, which we translated from the truth of Hebrew. But it signifies that before the doors of all the treasuries, or exedrae, and chambers, there was a walkway, having a width of ten cubits, which is a perfect number, either because of the Decalogue or because of the mystery of the Gospel. For if you come from one to four by twos and threes, the number ten is made, the number of the Gospels: in the width of which the priests walk, going before each treasury. But in such a way that they always look towards the interior of the path which leads to one cubit, that is, to the worship of one divinity, as the Son says to the Father: I have revealed thy name to men (John 17:6). For she is the way, looking inward, which is said in the Gospel: I am the way, and the truth, and the life (John XIV, 6): because no one comes to the knowledge of the Father, except through the Son.”
