Psalm 95:7-11 RSV

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.
10 For forty years I loathed that generation and said, "They are a people who err in heart, and they do not regard my ways."
11 Therefore I swore in my anger that they should not enter my rest.
