This jumps out to me as a short and happy eulogy.
(I can only think of an example or two that might be better.)
It says that Kind David died, “at a good old age.”
A Good Old Age – I like that phrase for some reason. It echos something of a life well-lived. A life without regret and work left undone.
Simply, King David’s time on earth was full with: Long life, riches, and honor.
We should all be so lucky…
26 Thus David the son of Jesse reigned over all Israel. 27 And the period that he reigned over Israel was forty years; seven years he reigned in Hebron, and thirty-three years he reigned in Jerusalem. 28 So he died in a good old age, full of days and riches and honor; and Solomon his son reigned in his place.
