Psalm 71:1-17 and Jeremiah 1:4-5, 17-19

Psalm 71:1-17
1 A Psalm of David. Of the sons of Jonadab and the former captives. In you, O Lord, I have hoped; do not let me be brought to ruin forever.
2 Free me by your justice, and rescue me. Incline your ear to me, and save me.
3 Be a God of protection and a place of strength for me, so that you may accomplish my salvation. For you are my firmament and my refuge.
4 Rescue me, O my God, from the hand of the sinner, and from the hand of the unjust and those who act against the law.
5 For you, O Lord, are my patience: my hope from my youth, O Lord.
6 In you, I have been confirmed from conception. From my mother's womb, you are my protector. In you, I will sing forever.
7 I have become to many as if I were a portent, but you are a strong helper.
8 Let my mouth be filled with praise, so that I may sing your glory, your greatness all day long.
9 Do not cast me off in the time of old age. Do not abandon me when my strength will fail.
10 For my enemies have spoken against me. And those who watched for my soul have taken counsel as one,
11 saying: "God has abandoned him. Pursue and overtake him. For there is no one to rescue him."
12 O God, do not be far from me. O my God, provide for my assistance.
13 May they be confounded, and may they fail, who drag down my soul. Let them be covered with confusion and shame, who seek evils for me.
14 But I will always have hope. And I will add more to all your praise.
15 My mouth will announce your justice, your salvation all day long. For I have not known letters.
16 I will enter into the powers of the Lord. I will be mindful of your justice alone, O Lord.
17 You have taught me from my youth, O God. And so I will declare your wonders continuously,
Jeremiah 1:4-5, 17-19
4 And the word of the Lord came to me, saying:
5 "Before I formed you in the womb, I knew you. And before you went forth from the womb, I sanctified you. And I made you a prophet to the nations."
17 Therefore, you should gird your waist, and rise up, and speak to them everything that I instruct you. You should not have dread before their face. For I will cause you to be unafraid of their countenance.
18 For certainly, this day, I have made you like a fortified city, and an iron pillar, and a brass wall, over all the land, to the kings of Judah, to its leaders, and to the priests, and to the people of the land.
19 And they will make war against you, but they will not prevail. For I am with you, says the Lord, so that I may free you."
