Psalms 95:8-11 NIV
“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.’ ”
NIV: New International Version
