Charles Ellicott Commentary Isaiah 14:22

"And I will rise up against them, saith Jehovah of hosts, and cut off from Babylon name and remnant, and son and son`s son, saith Jehovah." — Isaiah 14:22 (ASV)

Son, and nephew ... —The latter word, as throughout the Bible, is used in its true sense as “grandson” or “descendant” (compare 1 Timothy 5:4). Every word that could express descent is brought together to express the utter extirpation of the Babylonian dynasty. The Hebrew adds the emphasis of alliteration, as in our “bag and baggage,” and other like phrases.
