Theodoret of Cyrus
Why did Samuel, after anointing Saul and receiving divine revelation regarding his kingship, instruct the tribes to draw lots? Those who lived immorally were skeptical of God's messengers. To prevent any assumption that the decision stemmed from human judgment, Samuel commanded the lots to be cast. Subsequently, when the lot designated the tribe of Benjamin and was further divided into families and individuals, it ultimately pointed to Saul. Despite Saul's efforts to conceal himself, feeling unworthy of such authority, God revealed him to the Prophet, and the choice was validated by the consent of the entire assembly.
