Becoming a (great) nation

The concept of “becoming a (great) nation” or, having nations come out of you, though phrased differently, is common in and unique to P. P (17:6 17:16 17:20 28:3 35:11 46:3 48:4). A close reading of the above verses shows that they do not only agree in theme but there is much common language between them as well (though there is some variation. Note, this is in contrast to JE who speaks consistently about many descendants. The focus in P is on the forging of the nation, in JE about the multitude of the descendents.

One counter example is Gen 12:2 which is JE. Though the language there is slightly different than the P verses.
