Psalm 95:8-10

Amplified Bible

⁸ 
Do not harden your hearts and become spiritually dull as at Meribah [the place of strife],
And as at Massah [the place of testing] in the wilderness,^(A)
9 
“When your fathers tested Me,
They tried Me, even though they had seen My work [of miracles].
¹⁰ 
“For forty years I was grieved and disgusted with that generation,
And I said, ‘They are a people who err in their heart,
And they do not acknowledge or regard My ways.’
