Bede : These are therefore the chiefs of the families, etc. Until the end of the genealogy, he carefully enumerates the chiefs who went up with him from Babylon and explains their genealogy. He also endeavors to add the number of those, which reaches one thousand four hundred and forty, so that he may thus suggest that the names of those who ascend from the confusion of this world are written in the book of life of the Lamb. But also, each of the teachers, namely the chiefs of the families of God's people, receives eternal rewards to the extent of the number of souls they have brought to the Lord, according to that parable in the Gospel, where, with the good and prudent servant saying: Lord, your pound has gained ten pounds (Luke XIX), the master responds to him, saying: And you will be over ten cities; that is, you will appear more glorious in the heavenly kingdom from the lives of those whom you have taught. — Commentary on Ezra and Nehemiah
