Psalms 95:8-11

JPS_ASV_Byz(i) 8 'Harden not your heart, as at Meribah, as in the day of Massah in the wilderness; 9 When your fathers tried Me, proved Me, even though they saw My work. 10 For forty years was I wearied 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 swore in My wrath, that they should not enter into My rest.'
