Psalm 95:8-11

King James Version

⁸ Harden not your heart, as in the provocation, and as in the day of temptation in the wilderness:

⁹ When your fathers tempted me, proved me, and saw my work.

¹⁰ Forty years long was I grieved with this generation, and said, It is a people that do err in their heart, and they have not known my ways:

¹¹ Unto whom I sware in my wrath that they should not enter into my rest.
