Bede : Therefore, Sarai took his wife, and Lot his brother's son, and all the substance that they had gathered, and the souls that they had made in Haran; and they went forth to go into the land of Canaan. The phrase "the souls that they had made" is used to mean the children they had begotten. For in the Scriptures, a man is sometimes indicated by the name of the soul alone, sometimes by the name of the flesh alone. By "soul," as it is said: "The soul that sinneth, it shall die" (Ezekiel 18:20); by "flesh," as in the Psalm: "Unto thee shall all flesh come" (Psalms 65:3), since neither flesh without the soul can come to God, nor can the soul sin without the flesh, but the whole man is signified by one part. Nor do those who believe that as the flesh is generated from flesh, so the soul is generated from the soul have any support from this sentiment: for by the term "soul," as we have said, the whole man is understood. However, that they made souls, that is, procreated souls in Haran, should be understood not of Abraham and Lot, but of their household and servants: for the sacred history following this testifies that the patriarchs themselves still remained without children. — Commentary on Genesis (Hexaemeron)
