Psalms 95:8-11

Darby(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 was I grieved with the generation, and said, It is a people that do err in their heart, and they have not known my ways; 11 So that I swore in mine anger, that they should not enter into my rest.
