1 Samuel 10:23, “…And when he stood among the people, he was taller than any of the people from his shoulders upward.”
“From a human perspective, Saul fully satisfied the desires of the people. He was a man of great stature from the most military-minded tribe in all Israel and was considered capable of leading the people in battle against their enemies. Saul was also a man whose own spiritual life mirrored that of the majority of the Israelites, it was not long until he disobeyed the Lord (1 Sam. 13:8-14).
Nevertheless, the purposes of God are never circumvented by the wickedness of men, and David was chosen soon after Saul’s failure. Even if Saul had been obedient, his reign was destined to be temporary. The tribe of Judah, to which David belonged, was the one from which the King of Glory would come (Gen. 49:10).” ESV Hebrew-Greek Key Word Study Bible
I love the line…“the purposes of God are never circumvented by the wickedness of men.”
