Then Samuel took a flask of oil and poured it on his head and kissed him and said, “Has not the Lord anointed you to be prince over his people Israel? And you shall reign over the people of the Lord and you will save them from the hand of their surrounding enemies. And this shall be the sign to you that the Lord has anointed you to be prince over his heritage. When you depart from me today, you will meet two men by Rachel’s tomb in the territory of Benjamin at Zelzah, and they will say to you, ‘The donkeys that you went to seek are found, and now your father has ceased to care about the donkeys and is anxious about you, saying, “What shall I do about my son?”’ Then you shall go on from there farther and come to the oak of Tabor. Three men going up to God at Bethel will meet you there, one carrying three young goats, another carrying three loaves of bread, and another carrying a skin of wine. And they will greet you and give you two loaves of bread, which you shall accept from their hand. After that you shall come to Gibeath-elohim, where there is a garrison of the Philistines. And there, as soon as you come to the city, you will meet a group of prophets coming down from the high place with harp, tambourine, flute, and lyre before them, prophesying. Then the Spirit of the Lord will rush upon you, and you will prophesy with them and be turned into another man. Now when these signs meet you, do what your hand finds to do, for God is with you. Then go down before me to Gilgal. And behold, I am coming down to you to offer burnt offerings and to sacrifice peace offerings. Seven days you shall wait, until I come to you and show you what you shall do.” 1 Samuel 10:1-8.
Samuel anoints Saul, and then gives him some signs that this is real. After all, Saul just went out to find some donkeys, and the prophet just told him he would be Israel’s king. He could be excused for thinking that the prophet might have the wrong man.
In some ways he is right. This was not what God wanted. This came about because Israel demanded a king, and God took this as rejection. God was the rightful king, but the people wanted a king they could see.
We see this happen all the time. God wants our love and devotion, and we want an elected leader to live righteously for us. We set all our desire on winning earthly elections, and when we lose we are devastated. We forget that the important thing is our God and our obedience to Him.
