Psalm 89:2-29 and 2 Samuel 7:4-5a, 12-14a, 16

Psalm 89:2-29
2 I will sing the mercies of the Lord in eternity. I will announce your truth with my mouth, from generation to generation.
3 For you have said: Mercy will be built in the heavens, unto eternity. Your truth will be prepared there.
4 I have set up a covenant with my elect. I have sworn to David my servant:
5 I will prepare your offspring, even in eternity. And I will build up your throne, from generation to generation.
6 The heavens will confess your miracles, Lord, and also your truth, in the Church of the saints.
7 For who among the clouds is equal to the Lord? Who among the sons of God is like God?
8 God is glorified by the counsel of the saints. He is great and terrible above all those who are around him.
9 O Lord, God of hosts, who is like you? You are powerful, Lord, and your truth is all around you.
10 You rule over the power of the sea, and you even mitigate the movement of its waves.
11 You have humbled the arrogant one, like one who has been wounded. You have scattered your enemies with the arm of your strength.
12 Yours are the heavens, and yours is the earth. You founded the whole world in all its fullness.
13 You created the north and the sea. Tabor and Hermon will exult in your name.
14 Your arm acts with power. Let your hand be strengthened, and let your right hand be exalted.
15 Justice and judgment are the preparation of your throne. Mercy and truth will precede your face.
16 Blessed is the people that knows jubilation. They will walk in the light of your countenance, O Lord,
17 and they will exult in your name all day long, and they will be exalted in your justice.
18 For you are the glory of their virtue, and in your goodness, our horn will be exalted.
19 For our assumption is of the Lord, and it is of our king, the holy one of Israel.
20 Then you spoke in a vision to your holy ones, and you said: I have stationed help with the powerful one, and I have exalted the elect one from my people.
21 I have found my servant David. I have anointed him with my holy oil.
22 For my hand will assist him, and my arm will fortify him.
23 The enemy will have no advantage over him, nor will the son of iniquity be positioned to harm him.
24 And I will cut down his enemies before his face. And those who hate him, I will turn to flight.
25 And my truth and my mercy will be with him. And his horn will be exalted in my name.
26 And I will place his hand on the sea and his right hand on the rivers.
27 He will invoke me: "You are my father, my God, and the support of my salvation."
28 And I will make him the first-born, preeminent before the kings of the earth.
29 I will preserve my mercy for him eternally, and my covenant for him faithfully.
2 Samuel 7:4-5a, 12-14a, 16
4 But it happened in that night, behold, the word of the Lord came to Nathan, saying:
5 "Go, and say to my servant David: 'Thus says the Lord: 
12 And when your days will have been fulfilled, and you will sleep with your fathers, I will raise up your offspring after you, who will go forth from your loins, and I will make firm his kingdom.
13 He himself shall build a house to my name. And I will establish the throne of his kingdom, even forever.
14 I will be a father to him, and he shall be a son to me. 
​16 And your house shall be faithful, and your kingdom shall be before your face, for eternity, and your throne shall be secure continuously.' "
