Sorry if I came off harsh or priggish.
I googled “Dovid HaMelech middos” and among the many items that came up was the rothschild family blog with a bar mitzvah speech about Dovid Yaakov, which discusses
“the middos, character traits, of both Dovid ha Melech and Yaakov Avinu. .. Dovid ha Melech represents the midda of bitachon baShem, because without placing his trust in Hashem, Dovid would not have been able to overcome such adversity. He also represents the midda of malchus, kingship, which requires spiritual strength that is maximized through the midda of bitachon baShem….”
There is more there if you look. hatzlacha.
