"Precious in the sight of the LORD is the death of his saints", Psalm 116:15. That sounds strange, to hold anyone's death as precious, as if its one of your favourite moments in life!
But I reflected on the possibility that the Psalm is the cry of someone who feels abandoned by everyone (v11) and is in a life threatening position (v3). Faced with a lonely death and the thought that no one will mourn him the Psalm writer (David?) is able to take comfort that God cares about his death. If he dies, it won't be just a statistic or a minor upset, it will be an event close to God's heart.
