2nd book of Samuel 7,4-5a.12-14a.16. 
That night the LORD spoke to Nathan and said:
"Go, tell my servant David, 'Thus says the LORD: Should you build me a house to dwell in?
And when your time comes and you rest with your ancestors, I will raise up your heir after you, sprung from your loins, and I will make his kingdom firm.
It is he who shall build a house for my name. And I will make his royal throne firm forever.
I will be a father to him, and he shall be a son to me. And if he does wrong, I will correct him with the rod of men and with human chastisements;
Your house and your kingdom shall endure forever before me; your throne shall stand firm forever.'"
