Psalm 40:2-10 and 1 Samuel 3:1-10, 19-20

Psalm 40:2-10
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.
1 Samuel 3:1-10, 19-20
1 Now the boy Samuel was ministering to the Lord before Eli, and the word of the Lord was precious in those days; there was no manifest vision.
2 Then it happened that, on a certain day, Eli was lying in his place. And his eyes had dimmed, so that he was unable to see.
3 And so, to prevent the lamp of God from going out, Samuel was sleeping in the temple of the Lord, where the ark of God was.
4 And the Lord called Samuel. And responding, he said, "Here I am."
5 And he ran to Eli, and he said, "Here I am. For you called me." And he said: "I did not call. Return and sleep." And he went away, and he slept.
6 And again, the Lord continued to call to Samuel. And rising up, Samuel went to Eli, and he said: "Here I am. For you called me." And he responded: "I did not call you, my son. Return and sleep."
7 Now Samuel did not yet know the Lord, and the word of the Lord had not been revealed to him.
8 And the Lord continued, and he called to Samuel still a third time. And rising up, he went to Eli.
9 And he said: "Here I am. For you called me." Then Eli understood that the Lord had called the boy. And he said to Samuel: "Go and sleep. And if he calls to you from now on, you will say, 'Speak, Lord, for your servant is listening.' " Therefore, Samuel went away, and he slept in his place.
10 And the Lord came, and stood, and he called, just as he had called the other times, "Samuel, Samuel." And Samuel said, "Speak, Lord, for your servant is listening."
​19 And Samuel grew up, and the Lord was with him, and not one of his words fell to the ground.
20 And all of Israel, from Dan even to Beersheba, knew Samuel to be a faithful prophet of the Lord.
