'Forever' in the Bible

Then Bathsheba knelt with her face to the ground and did obeisance to the king, and she said, "May my lord, King David, live forever."

And their blood will return on the head of Joab and on the head of his descendants forever, but for David and his descendants and for his house and his throne, [there] will be peace forever from Yahweh."

but King Solomon will be blessed and the throne of David will be established before Yahweh forever."

I have certainly built a lofty house for you, a place for you to live forever."

Yahweh said to him, "I have heard your prayer and your plea which you have made before me. I have consecrated this house which you have built, by putting my name there forever. My eyes and my heart will always be there.

then I will establish the throne of your kingdom over Israel forever, as I promised David your father, saying, 'A man will not be cut off for you from upon the throne of Israel.'

May Yahweh your God be blessed, who has delighted in you to set you on the throne of Israel, because of the love of Yahweh for Israel forever, and he has made you king to execute justice and righteousness."
