Gen 10, 1…32 These are the descendants of Noah's sons

Genesis 10

(Gen 10, 1…32) These are the descendants of Noah's sons

[1] These are the descendants of Noah's sons, Shem, Ham, and Japheth, to whom sons were born after the flood. … [32] These are the groupings of Noah's sons, according to their origins and by their nations. From these the other nations of the earth branched out after the flood.

(CCC 56) After the unity of the human race was shattered by sin God at once sought to save humanity part by part. The covenant with Noah after the flood gives expression to the principle of the divine economy toward the "nations", in other words, towards men grouped "in their lands, each with (its) own language, by their families, in their nations" (Gen 10:5; cf. 9:9-10, 16; 10:20-31).
