Today's reading describes David's final discourse before his death, in which he used his wisdom to describe the years ahead for the Israelites. (Similar final discourses/blessings are given by Jacob, Moses, and Joshua.) In it, David is focused completely on the Temple. First, he gave Solomon detailed plans for the Temple's construction, then he led the fundraising effort for the holy objects to be used inside the Temple, including lavish gifts from his personal fortune. Then, after a final prayer praising God, David died and power is transferred to Solomon.
