So shall their blood return on the head of Joab and the heads of his descendants forever. But for David, his descendants, his house, and his throne, may there be peace from the Lord forever.”

But King Solomon shall be blessed, and the throne of David shall be established before the Lord forever.”

“I have certainly built You a lofty house,A place for You to dwell in forever.”

The Lord told him, “I have heard your prayer and supplication which you have made before Me; I have consecrated this house which you have built by putting My Name and My Presence there forever. My eyes and My heart shall be there perpetually.

then I will establish the throne of your kingdom over Israel forever, just as I promised your father David, saying, ‘You shall not be without a man (descendant) on the throne of Israel.’

Blessed be the Lord your God who delighted in you to set you on the throne of Israel! Because the Lord loved Israel forever, He made you king to execute justice and righteousness.”

And in this way I will afflict the descendants of David for this (their sin), but not forever.’”

They spoke to him, saying, “If you will be a servant to this people today, and will serve them and grant their request, and speak good words to them, then they will be your servants forever.”
