Bede : Note that [Paul] taught Greeks in Jerusalem, and Jews in Damascus which is a Gentile city, even though this should signify that Gentiles were to be included in the city of God and Jews were to fall into the faithlessness of the Gentiles, in accordance with what Isaiah said, "Lebanon shall be changed into Carmel, and Carmel shall be regarded as a wasteland." — Commentary on Acts 9 Jerome : (Verse 17). Will not Lebanon soon become a fruitful field, and the fruitful field be regarded as a forest? Let the Jews and friends of simple history answer, those who seek fruit not on the tree, but only leaves and the shadow of words, which quickly wither and perish. How is it that in the coming of the Lord Savior (because from the time of Isaiah until the incarnation of the flesh, for the comparison of eternity, it is a short and small span of time) the mountain of Lebanon turned towards Phoenicia and moved to Mount Carmel? It is called in Hebrew Chermel, and it is near the border of Palestine and Phoenicia, overlooking Ptolemais: although another mountain in the holy scriptures is called Mount Carmel, where there was Nabal the Carmelite (1 Samuel 25), a foolish and wicked man, who had a wife named Abigail, who married David after her husband died; while her husband was alive, she could not marry David, so as not to be called an adulteress if she were associated with another man; and how is Carmel considered a desirable place and unfruitful trees? But since they are unable to express it, let them listen to Libanus, which means "whiteness", referring to the people of the Gentiles who, having been washed in the Lord and cleansed of their former filth, ascend as a whole world. They rely on the person of the Church as the bride of the Savior, and it is said about them in the Song of Songs: Who is this who comes up, shining white, leaning on her beloved? (Cant. VIII. 5) And let this people be transferred to Carmel, which means the knowledge of circumcision, so that they may recognize the mysteries of spiritual and true circumcision, and be in the place of the former people of the Jews. As for those who refuse to accept Christ, let them be considered as thorns and barren trees, which cannot praise the Lord with fruitful trees. — Commentary on Isaiah
