Judges 5:3

The fourth song is in the book of Judges, concerning which it is written: "And Deborah and Barak the son of Abinoam sang on that day, saying: When the leaders in Israel began, in the purpose of the people, bless ye the Lord. Hear, O kings, and give ear," and the rest. But she who sings these things ought to be a bee, whose work is such that both kings and ordinary folk use it for health. For Deborah, who sings this song, is interpreted "a bee," and Barak too along with her: and Barak is interpreted "lightning-flash." And this song is sung after victory, because no one can sing what is perfect until he has conquered his adversaries. So, finally, in the song itself it is said: "Arise, arise, Deborah, rouse up the thousands of the people. Arise, arise, sing a song, arise, Barak." But concerning these things too you will find matters more fully discussed in those little discourses which we have published on the book of Judges.

Hear, O kings. She names them "kings" who are called together to hear the word of God. You should rejoice, people of God, at this emblem of your nobility. It is not as just any people that you are called to hear the word of God, but as a king, for to you it was said, "You are a royal, priestly race, a people for God's possession." Because you are kings, therefore, Christ our Lord is rightly called the "King of kings and the Lord of lords." However, as you revel in this title of your nobility, you should also learn what each one of you must do to be a king. Let me outline it for you briefly. You are made a king if Christ reigns in you, for he is called a king by reigning. If also in you, therefore, the soul reigns and the body submits, if you put the concupiscence of the flesh under of yoke of your command, if you subdue every kind of vice by the tight bridle of your sobriety, then you who know how to reign are also rightly called a "king."
