Theodoret of Cyrus
Why did Samuel, after anointing Saul and receiving divine revelation regarding his kingship, instruct the tribes to draw lots? Those who engaged in corrupt practices did not heed the words of God's messengers. To prevent the notion that human compassion influenced the decision, Samuel mandated the casting of lots. When the lot designated the tribe of Benjamin and was further narrowed down through generations, households, and individuals, it ultimately fell to Saul. Although Saul sought to conceal himself, feeling unworthy of such power, God revealed him to the Prophet, affirming his selection in the eyes of the entire assembly.
