Reading 1, Second Samuel 7:4-5, 12-14, 16

4 But that very night, the word of Yahweh came to Nathan:

5 'Go and tell my servant David, "Yahweh says this: Are you to build me a temple for me to live in?

12 And when your days are over and you fall asleep with your ancestors, I shall appoint your heir, your own son to succeed you (and I shall make his sovereignty secure.

13 He will build a temple for my name) and I shall make his royal throne secure for ever.

14 I shall be a father to him and he a son to me; if he does wrong, I shall punish him with a rod such as men use, with blows such as mankind gives.

16 Your dynasty and your sovereignty will ever stand firm before me and your throne be for ever secure." '

Responsorial Psalm, Psalms 89:2-3, 4-5, 27, 29

2 for you have said: love is built to last for ever, you have fixed your constancy firm in the heavens.

3 'I have made a covenant with my Chosen One, sworn an oath to my servant David:

4 I have made your dynasty firm for ever, built your throne stable age after age.'Pause

5 The heavens praise your wonders, Yahweh, your constancy in the gathering of your faithful.

27 So I shall make him my first-born, the highest of earthly kings.

29 I have established his dynasty for ever, his throne to be as lasting as the heavens.

19 Her husband Joseph, being an upright man and wanting to spare her disgrace, decided to divorce her informally.

18 Though there seemed no hope, he hoped and believed that he was to become father of many nations in fulfilment of the promise: Just so will your descendants be.

22 This is the faith that was reckoned to him as uprightness.
