Psalm 40:2-18 and Jeremiah 38:4-6, 8-10

Psalm 40:2-18
2 I have waited expectantly for the Lord, and he was attentive to me.
3 And he heard my prayers and he led me out of the pit of misery and the quagmire. And he stationed my feet upon a rock, and he directed my steps.
4 And he sent a new canticle into my mouth, a song to our God. Many will see, and they will fear; and they will hope in the Lord.
5 Blessed is the man whose hope is in the name of the Lord, and who has no respect for vanities and absurd falsehoods.
6 You have accomplished your many wonders, O Lord my God, and there is no one similar to you in your thoughts. I have announced and I have spoken: they are multiplied beyond number.
7 Sacrifice and oblation, you did not want. But you have perfected ears for me. Holocaust and sin offering, you did not require.
8 Then I said, "Behold, I draw near." At the head of the book, it has been written of me:
9 that I should do your will. My God, I have willed it. And your law is in the midst of my heart.
10 I have announced your justice in a great Church: behold, I will not restrain my lips. O Lord, you have known it.
11 I have not concealed your justice within my heart. I have spoken your truth and your salvation. I have not concealed your mercy and your truth from a great assembly.
12 O Lord, do not take your tender mercies far from me. Your mercy and your truth ever sustain me.
13 For evils without number have surrounded me. My iniquities have taken hold of me, and I was not able to see. They have been multiplied beyond the hairs of my head. And my heart has forsaken me.
14 Be pleased, O Lord, to rescue me. Look down, O Lord, to help me.
15 Let them together be confounded and awed, who seek after my soul to steal it away. Let them be turned back and be in awe, who wish evils upon me.
16 Let them bear their confusion all at once, who say to me, "Well, well."
17 Let all who seek you exult and rejoice over you. And let those who love your salvation always say, "May the Lord be magnified."
18 But I am a beggar and poor. The Lord has been concerned about me. You are my helper and my protector. My God, do not delay.
Jeremiah 38:4-6, 8-10
4 And the leaders said to the king: "We petition you to put this man to death. For he is deliberately weakening the hands of the men of war, who have remained in this city, and the hands of the people, by speaking to them with these words. For this man is certainly not seeking peace for this people, but evil."
5 And king Zedekiah said: "Behold, he is in your hands. For it is not fitting for the king to deny you anything."
6 Therefore, they took Jeremiah and cast him into the pit of Malchiah, the son of Amelech, which was at the entrance to the prison. And they lowered Jeremiah by ropes into the pit, in which there was no water, but only mud. And so Jeremiah descended into the mire.
8 And so Ebedmelech departed from the king's house, and he spoke to the king, saying:
9 "My lord the king, these men have done evil in all that they have perpetrated against Jeremiah the prophet, casting him into the pit so that he would die there from famine. For there is no more bread in the city."
10 And so the king instructed Ebedmelech, the Ethiopian, saying: "Take with you thirty men from here, and lift Jeremiah the prophet from the pit, before he dies."
