'Closest' in the Bible

“If your brother, the son of your mother, or your son or daughter, or the wife you embrace, or your closest friend secretly entices you, saying, ‘Let us go and worship other gods’—which neither you nor your fathers have known,

You shall build a roadway and divide into thirds the whole extent of your land that the Lord your God is providing as your inheritance; anyone who kills another person should flee to the closest of these cities.
