Genesis 36:10

These are the names Observe here, 1st, That only the names of Esau's sons and grandsons are recorded: not their history, for it is the Church that Moses preserves the records of, not of those that were without. The elders only, that lived by faith, obtained a good report. 2d, That the sons and grandsons of Esau are called dukes. Probably they were military commanders, that had soldiers under them; for Esau and his family lived by the sword, Genesis 27:40. 3d, We may suppose those dukes had numerous families of children and servants. God promised to multiply Jacob and to enrich him; yet Esau increases and is enriched first. God's promise to Jacob began to work late, but the effect of it remained longer, and it had its complete accomplishment in the spiritual Israel.
