John Trapp on Psalms 78:35

Verſ. 35. And they remembred] Miſery is the beſt art of memory. But this remembrance of God was but as letters written in the ſand, or as a picture drawn on the Ice, that long continueth not; 'twas but a flaſh, and while they were in a good mood; 'twas but as Nebuchadnezzars dream, which he had ſoon forgotten. They remembred God, lingua non corde, with the tongue, but not with the heart. as Aben-Ezra here gloſſeth. They gave God a meſſe of fair words, calling him Rock, Redeemer, &c. but he is not to be ſo courted and complemented, Goats may be fed with leaves, but God is not mocked.
