Matthew Henry on 1 Chronicles 5:1-17
We have here an extract out of the genealogies,
I. Of the tribe of Reuben, where we have,
1. The reason why this tribe is thus postponed. It is confessed that Reuben was the first-born of Israel, and, upon that account, might challenge the precedency; but he forfeited his birthright by defiling his father's concubine, and was, for that, sentenced not to excel, Gen 49:4. Sin lessens men, thrusts them down from their excellency. Seventh-commandment sins especially leave an indelible stain upon men's names and families, a reproach which time will not wipe away.
