Thus much we may say concerning breadth. We must now consider who it is who Noah prays may dwell in the tents of Shem, for he does not say very clearly. One may affirm that he means the Lord of the universe; for what more suitable and beautiful abode in all creation could be found for God beyond a soul completely purified, and
 Genesis ix. 26. 

 
thinking nothing beautiful but what is good, and looking upon all things, which are usually held in estimation among men, in the light of subjects and body-guards of that one thing, good? But God is said to dwell in a house, not as in respect of place (for he contains everything and is contained by nothing), but as in a most especial degree exerting his providence and care in favour of that place; for it follows inevitably in the case of every one who is master of a house that he has a particular care for that house.
 But let every one, on whom the love of God has showered good things, pray to God that he may have as a dweller within him the Ruler of all things, who will raise this small house, the mind, to a great height above the earth, and will connect it with the bounds of heaven. And what is said in the scriptures appears to coincide with this, for Shem is planted as a root of excellence and virtue; and from this root there sprang up a tree bringing forth good fruit, namely, Abraham, of whom the self-instructed and self-teaching offspring, Isaac, was the fruit, by whom again the virtues which are displayed in labour are sown, the practiser of which is Jacob, the man trained and exercised in wrestling with the passions, having the admonitions of angels for his gymnastic trainers.
