Hebrews 3:8-10

ISV(i) 8 do not harden your hearts as they did when they provoked me during the time of testing in the wilderness. 9 There your ancestors tested me, even though they had seen my actions 10 for 40 years. That is why I was indignant with that generation and said, ‘They are always going astray in their hearts, and they have not known my ways.’
