To place a crown on a person's head is a sign of making him king. Alternate translation: "I have made a mighty man king" (See: [[rc://en/ta/man/translate/translate-symaction]])
Here "raised up" means appointed. It is implied that God chose this person to be king. Alternate translation: "I have chosen one from among the people to be king" (See: [[rc://en/ta/man/translate/figs-idiom]] and [[rc://en/ta/man/translate/figs-explicit]])
