John Trapp on Nehemiah 9:14

Verſe 14. And madeſt known unto them thy holy Sabbath.] Not then firſt known to the Church: but of old obſerved, even from the beginning, Gen. 2.3. about 2544. years before it was made known in ſuch a ſolemne ſort at Sinai; as having been much neglected and forgotten, during the Egyptian ſervitude. So it was by the German Churches, till God awakened them by the loſſe of Prague (that firſt blow given them) and that upon the Sabbath day, which they kept no otherwiſe then if it had been Dies daemoniacus, and not dominicus, (as their countrey-man Alſted complaineth) and as if it had been called Sabbath from Sabbos a name of Bacchus, as Plutarch dreamed.

And commandedſt them precepts] See the Note on verſe 13.
