Poole on 1 Chronicles 1:4-7: The Sons of Japheth

Verse 4:[1] Noah, Shem, Ham, and Japheth.

[Noah, Shem, etc.] Understand, Noah begat Shem, Ham, and Japheth (Mariana,[2] Tirinus,[3] similarly Vatablus): and thus this verse ought to be expounded differently than the former verses. He had to make mention only of the one son, etc., from whom Abraham and David descended: but, because of their nobility, and because after the flood they occupied and replenished the three parts of the world, he lists all those three and their generation (Vatablus).

Shem, Ham, and Japheth: Formerly he mentions only one son, but here he names and treats of Noah’s three sons, partly because they were all the founders of the new world, and partly because the accomplishment of Noah’s famous prophecy, Genesis 9:25-27, could not otherwise appear, but by the account of their several posterities.

Verse 5:[4] (Gen. 10:2, etc.) The sons of Japheth; Gomer, and Magog, and Madai, and Javan, and Tubal, and Meshech, and Tiras.

[The sons of Japheth; Gomer] He proceeds in reverse order: for he begins with the third son of Noah (Vatablus). See on Genesis 10:2 (Piscator[5]).

Verse 6:[6] And the sons of Gomer; Ashchenaz, and Riphath (or, Diphath, as it is in some copies), and Togarmah.

[Riphath] Thus it is found in Genesis 10:3[7] (Menochius, Mariana), and here in the Septuagint, Jerome, and in the book of the Masorah[8] (Mariana). Hebrew: דִּיפַת/Diphath. The ד/d and ר/r, because of their great similarity, are easily exchanged, as we shall see below in verses 7, 41, 46, 50 (Malvenda,[9] thus Mariana, Bochart’s A Sacred Catalogue of Animals[10] 2:2:8:191).

Riphath, or Diphath; for those two Hebrew letters which answer to our D (ד) and R (ר), being very like, are oft confounded and exchanged, as 1 Chronicles 1:7, 41, 46, 50.
