Psalms 80:8

In the secret place of tempest. Hebrew, of thunder. When thou soughtest to hide thyself from the tempest: or, when I came down to Mount Sinai, hidden from the eyes in a storm of thunder; (Challoner; Exodus xix. 16.) or when I afflicted Egypt, (Exodus ix. 23.) and Pharao's army, Psalm lxxvi. 19. --- Contradiction, at Mara, or rather at Cades, where Moses betrayed some distrust, Exodus xxiv. 25., and Numbers xx. 12. (Calmet) --- After so many benefits, they still contradicted God, and would not serve him. (Worthington)
