Psalms 95:8-11

ERV(i) 8 Harden not your heart, as at Meribah, as in the day of Massah in the wilderness: 9 When your fathers tempted me, proved me, and saw my work. 10 Forty years long was I grieved with [that] generation, and said, It is a people that do err in their heart, and they have not known my ways: 11 Wherefore I sware in my wrath, that they should not enter into my rest.
