Jeremiah 7:23-28.

Thus says the LORD: This is what I commanded my people: Listen to my voice; then I will be your God and you shall be my people. Walk in all the ways that I command you, so that you may prosper. 
But they obeyed not, nor did they pay heed. They walked in the hardness of their evil hearts and turned their backs, not their faces, to me. 
From the day that your fathers left the land of Egypt even to this day, I have sent you untiringly all my servants the prophets. 
Yet they have not obeyed me nor paid heed; they have stiffened their necks and done worse than their fathers. 
When you speak all these words to them, they will not listen to you either; when you call to them, they will not answer you. 
Say to them: This is the nation which does not listen to the voice of the LORD, its God, or take correction. Faithfulness has disappeared; the word itself is banished from their speech. 

Psalms 95(94):1-2.6-7.8-9. 

Come, let us sing joyfully to the LORD; 
let us acclaim the Rock of our salvation. 
Let us come into his presence with thanksgiving; 
let us joyfully sing psalms to him. 

Come, let us bow down in worship; 
let us kneel before the LORD who made us. 
For he is our God, 
and we are the people he shepherds, the flock he guides. 

“Harden not your hearts as at Meribah, 
as in the day of Massah in the desert, 
Where your fathers tempted me; 
they tested me though they had seen my works.”
