The phrase “lord king David” is found in 1 Kings Chapter 1 (vs. 31, 37, 43, 47)—this is in the King James Bible. Well, King James, who commissioned the 1611 translation, and of whom the Version’s namesake comes from, is honored in the Mayflower Compact and called “Lord King James”. Those Englishmen were honoring their king (see 1 Pet. 2:17) like the Israelites did for their king David (and there’s nothing wrong with that): and those pilgrims learned about that from the Holy Bible that James had translated. By the way, James is a Biblical name, and the Mayflower Compact proves King James was the founding monarch of America; and his Bible translation was completed approximately at the same time. Also, Jesus Christ our Saviour has a three part name: “Lord Jesus Christ”—this conveys the Trinity (see 1 John 5:7 KJV). Amen.
