Following this thread on the Geneva Triumvirate, I was wondering if anyone can identify for me the names of Herman Witsius' Quadrumvirate of pastors mentioned by him in Twist des Heeren met syn Wijngaert (The Lord's Controversy with His Vineyard).

Joel R. Beeke & Randall J. Pederson, Meet the Puritans, pp. 810-811:

Witsius accepted a call to Goes in 1666, where he labored for two years. In the preface to Twist des Heeren met syn Wijngaert (The Lord's Controversy with His Vineyard), published in Leeuwarden in 1669, he said that he had labored with much peace in this congregation together with three colleagues, "two of whom were venerated as fathers, and the third was loved as a brother." Of these four ministers working together in one congregation, Witsius noted: "We walked together in fellowship to God's house. We did not only attend each other's services, but also each other's catechism classes and other public services, so that what one servant of God might have taught yesterday, the others confirmed and recommended to the congregation the next day." Under the influence of these four ministers, "all sorts of devotional practices blossomed, piety grew, and the unity of God's people was enhanced," Witsius wrote.
