John Trapp on Psalms 78:36

Verſ. 36. Nevertheleſs they did flatter him with their mouth] They looked pittifully, as the Fox caught in a gin doth, but it is only to get out; they ſpake God fair, as the Devil in the Goſpel did our Saviour, but it was only to be rid of him. They worſhiped him, as the Indians do the Devil, that he may do them no hurt. The Latine word Colo, to worſhip, is by ſome derived of the Greek word [non-Latin text not transcribed] to flatter, and the Engliſh word flatter, from the Greek [non-Latin text not transcribed] to worſhip. Sure it is that many mens devotion is meer diſſimulation.

And they lyed unto him] ſc. Whiles they called him Rock Redeemer, and all was but from the teeth outward; which how much God abhorreth as a ludibrious devotion, ſee Jer. 3.4, 5. And here is ſaid to be the middle of the Pſalter; for hither to the Hebrews reckon one thouſand two hundred ſixty and three verſes; and as many they note to be yet left in the Second part.
