five hundred yeares old] Heb. a sonne of five hundred yeares. Not compleat but current, that is, now living on towards the end of the five hundreth yeare since he was first a sonne to his father; as when a Levite entred upon his service of the Tabernacle, being a sonne of thirty yeares, Numbers 4:3. the meaning is, that his age passeth on towards the end of thirty yeares. Noah begat] That is, began to beget: For he had not all three in one yeare; nor now first of all: for it is not like he continued five hundred yeares single, but that he was a father before this time, though his former children (it is like) were dead before the Flood.
