Psalm 95:7-9 Revised Standard Version Catholic Edition (RSVCE)
7 For he is our God,
and we are the people of his pasture,
and the sheep of his hand.
O that today you would hearken to his voice!
8 Harden not your hearts, as at Mer′ibah,
as on the day at Massah in the wilderness,
9 when your fathers tested me,
and put me to the proof, though they had seen my work.
