Psalm 95:8-11

do not harden your hearts, as at Meribah, as on the day at Massah in the wilderness, when your fathers put me to the test and put me to the proof, though they had seen my work. For forty years I loathed that generation and said, “They are a people who go astray in their heart, and they have not known my ways.” Therefore I swore in my wrath, “They shall not enter my rest.”
