這首《葡萄園之歌》是一部文學傑作，因為它蘊含著豐富的意義層次，並能引發讀者理解上的轉變。

歌曲開始，它是一首情歌：葡萄園被賦予了另一種——傳統的——象徵意義：它代表著對男友的愛不予回應的女友。

然而，當談到懲罰時，男友突然變成了另一個人：一個擁有強大力量，能夠遮蔽天空，阻止雨水降臨的人。

於是，第三層意義浮現：葡萄園象徵以色列人，他們沒有以公義的果實來回應上主的愛。

聽眾的情緒也隨之轉變：起初，他們被這愛情故事所感動、微笑；起初，他們認同對葡萄園女友的懲罰，但隨後，他們突然意識到，他們正在上主的愛面前自我譴責，而他們卻以壓迫和暴力來回應這份愛。

在新約聖經中，耶穌會使用同樣的葡萄園意象，但意義卻發生了巨大的變化：在舊約中，葡萄園就是被揀選的人民；在福音書中，被揀選的人民只是掌管葡萄園，也就是天國：他們可能會被排除在外。

This “Song of the Vineyard” is a literary masterpiece, because of the many layers of meaning and changes of comprehension it produces in the readers.

It starts as a love song: the vineyard receives an additional – and traditional – meaning: it represents the girlfriend, who does not respond to the love of his boyfriend.

However, when talking about the punishment, the boyfriend suddenly represents somebody else: somebody who is powerful enough to close the skies and not let the rain come.

So, the third meaning looms: the vineyard represents the people of Israel, who do not respond with fruits of justice to the love of God.

The listeners’ mood too changes: from smile at the love’s story, from agreeing to the punishment inflicted to the vineyard-girlfriend, they suddenly realize that they are condemning themselves in front of God’s love, to which they respond with oppression and violence.

In the NT, Jesus will use the same image of the vineyard, however with a huge change: in the OT the vineyard is the chosen people; in the Gospel, the Chosen people is just in charge of the vineyard, the Kingdom of Heaven: they can be excluded from it.
