Psalms 95:8-11

“Do not harden your hearts as you did at Meribah, as you did that day at Massah in the wilderness, where your ancestors tested me; they tried me, though they had seen what I did. For forty years I was angry with that generation; I said, ‘They are a people whose hearts go astray, and they have not known my ways.’ So I declared on oath in my anger, ‘They shall never enter my rest.’ ”
