John Trapp on Proverbs 21:30

Verſ. 30. There is wiſdome againſt the Lord] That is, they are all to no purpoſe. If God deny concourſe and influence, the arm of humane power and policy (as Jeroboams) ſhrinks up preſently. See Pſal. 2.1, 2, 3. & 33.10, 11. & 62.3. See the Note on Chap. 19.21. Excellently Gregory, Divinum conſilium dum devitatur, impletur: humana ſapientia dum reluctatur, comprehenditur. Gods decree is fulfilled, by thoſe that have leaſt minde to it: Humane wiſdome, whiles it ſtrives for maſteries, is over-maſtered.
