1 Samuel 9:27

And when they descended to the outermost part of the city, Samuel said to Saul, etc. When the Lord was sitting, having assumed humility and poverty for us, revealing Himself as the most despised and last of men, and among the citizens of the world as the lowest, He also taught His followers to be poor in spirit, yet He did not immediately face death at the hands of the often impious plotters; but according to the prophecies, of which John is a part, He commanded His obedient servants to go before Him, and to pass from vices to virtues, from death to life. But He Himself remained in the world for a little while after they departed until He completed the word about Him foretold by the prophets to His faithful.

But what was done next follows: "And as they were going down to the outskirts of the city, Samuel said to Saul: Tell the servant to go ahead of us and pass on; but you stand still for a moment, that I may make known to you the word of the Lord. Then Samuel took a flask of oil and poured it on his head, and kissed him." For what does it mean that the king is led to the farthest part of the city and anointed? But the farthest part of the city is the lowest part of the subject people. Those who therefore hold the last place in the holy Church are, as it were, in the farthest part of the city. Moreover, in the lowest part of the Church itself, converted sinners appear to be. For all the righteous are in the upper or first part. Or perhaps virginity holds the first place, continence the second, the married life the third, and the conversion of sinners the last. In the farthest part of the city, therefore, the king is anointed: because the ruler of the holy Church is ordained for sinners, not for the righteous. For hence Truth says of Himself: "I came not to call the righteous, but sinners to repentance" (Matt. 9:13). Hence again He says: "They that are whole need not a physician, but they that are sick" (ibid., 12).
