Psalm 51:12-19 and Jeremiah 31:31-34

Psalm 51:12-19
​12 Create a clean heart in me, O God. And renew an upright spirit within my inmost being.
13 Do not cast me away from your face; and do not take your Holy Spirit from me.
14 Restore to me the joy of your salvation, and confirm me with an unsurpassed spirit.
15 I will teach the unjust your ways, and the impious will be converted to you.
16 Free me from blood, O God, the God of my salvation, and my tongue will extol your justice.
17 O Lord, you will open my lips, and my mouth will announce your praise.
18 For if you had desired sacrifice, I would certainly have given it, but with holocausts, you will not be delighted.
19 A crushed spirit is a sacrifice to God. A contrite and humbled heart, O God, you will not spurn.
Jeremiah 31:31-34
31 Behold, the days are approaching, says the Lord, when I will form a new covenant with the house of Israel and with the house of Judah,
32 not according to the covenant which I made with their fathers, in the day when I took them by the hand, so as to lead them away from the land of Egypt, the covenant which they nullified, though I was the ruler over them, says the Lord.
33 But this will be the covenant that I will form with the house of Israel, after those days, says the Lord: I will give my law to their inner most being, and I will write it upon their heart. And I will be their God, and they shall be my people.
34 And they will no longer teach, a man his neighbor, and a man his brother, saying: 'Know the Lord.' For all will know me, from the littlest of them even to the greatest, says the Lord. For I will forgive their iniquity, and I will no longer remember their sin.
