Old Testament: 

Jeremiah 15:10-21

10 Woe is me, my mother, that you bore me, a man of strife and contention to the whole land! I have not lent, nor have I borrowed, yet all of them curse me. 11 The Lord said, “Have I not set you free for their good? Have I not pleaded for you before the enemy in the time of trouble and in the time of distress? 12 Can one break iron, iron from the north, and bronze?

13 “Your wealth and your treasures I will give as spoil, without price, for all your sins, throughout all your territory. 14 I will make you serve your enemies in a land that you do not know, for in my anger a fire is kindled that shall burn forever.”

15 O Lord, you know;
remember me and visit me,
and take vengeance for me on my persecutors.
In your forbearance take me not away;
know that for your sake I bear reproach.
16 Your words were found, and I ate them,
and your words became to me a joy
and the delight of my heart,
for I am called by your name,
O Lord, God of hosts.
17 I did not sit in the company of revelers,
nor did I rejoice;
I sat alone, because your hand was upon me,
for you had filled me with indignation.
18 Why is my pain unceasing,
my wound incurable,
refusing to be healed?
Will you be to me like a deceitful brook,
like waters that fail?

19 Therefore thus says the Lord:
“If you return, I will restore you,
and you shall stand before me.
If you utter what is precious, and not what is worthless,
you shall be as my mouth.
They shall turn to you,
but you shall not turn to them.
20 And I will make you to this people
a fortified wall of bronze;
they will fight against you,
but they shall not prevail over you,
for I am with you
to save you and deliver you,
declares the Lord.
21 I will deliver you out of the hand of the wicked,
and redeem you from the grasp of the ruthless.”

New Testament:

Hebrews 4:1-13

4 Therefore, while the promise of entering his rest still stands, let us fear lest any of you should seem to have failed to reach it. 2 For good news came to us just as to them, but the message they heard did not benefit them, because they were not united by faith with those who listened. 3 For we who have believed enter that rest, as he has said,

“As I swore in my wrath,
‘They shall not enter my rest,’”

although his works were finished from the foundation of the world. 4 For he has somewhere spoken of the seventh day in this way: “And God rested on the seventh day from all his works.” 5 And again in this passage he said,

“They shall not enter my rest.”

6 Since therefore it remains for some to enter it, and those who formerly received the good news failed to enter because of disobedience, 7 again he appoints a certain day, “Today,” saying through David so long afterward, in the words already quoted,

“Today, if you hear his voice,
do not harden your hearts.”

8 For if Joshua had given them rest, God would not have spoken of another day later on. 9 So then, there remains a Sabbath rest for the people of God, 10 for whoever has entered God's rest has also rested from his works as God did from his.

11 Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience. 12 For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart. 13 And no creature is hidden from his sight, but all are naked and exposed to the eyes of him to whom we must give account.
