In religio-mythology, Japheth, from the Hebrew Ja- ‘god’ + Egyptian ‘-ptah’, is the Judaeo recension rescript of the Egyptian god Ptah (Greenberg, 2000), recast into the Biblical story of him being one of the three sons, along with Shem (Ogdoad) and Ham (keme), of the flood man Noah (water god Nun).

Quotes
The following are related quotes:

“Turning to the Egyptian sphere, though, again we have a connection. The name Japheth in old Hebrew consists of three consonants, ‘J-Ph-Th’. The ‘ph’ and ‘th’ sounds are linguistically equivalent to ‘p’ and ‘t’, so we can write the name as J-PT. In Hebrew, when combining the name of god with another word, one would use a ‘J’ for god's name, which usually appears in transliteration as ‘Ja’ [Ja-Pheth / god Ptah] or ‘Jo’ [Jo-seph / Joseph / god Geb]. In J-PT, the PT part of the name contains the same letters used for the name of the Memphite creator deity, Ptah, so Japheth would be the linguistic equivalent of the name ‘god-Ptah’. This is a typical form of Egyptian combination name, such as Atum-Re [Atum-Ra] or Re-Herakhte. It also suggests the frequently used Hebrew term ‘lord god’.”
