1 Chronicles 2:6 - Wesley's Explanatory Notes

Dara — If these be the same who are mentioned as the sons of Machol, 1 Kings 4:31, either the same man had two names, Zerah and Machol, as was usual among the Hebrews: or, one of these was their immediate father, and the other their grand — father. These are named, because they were the glory of their father's house. When the Holy Ghost would magnify the wisdom of Solomon, he saith, he was wiser than these four men. That four brothers should be so eminent, was a rare thing.
