“I am the true vine, and my Father is the vinedresser. Every branch of mine that bears no fruit, he takes away, and every branch that does bear fruit he prunes, that it may bear more fruit. You are already made clean by the word which I have spoken to you. Abide in me, and I in you. As the branch cannot bear fruit by itself, unless it abides in the vine, neither can you, unless you abide in me. I am the vine, you are the branches. He who abides in me, and I in him, he it is that bears much fruit, for apart from me you can do nothing.” (RSV-CE Jn. 14: 6-7)
"Let me sing for my beloved a love song concerning his vineyard: My beloved had a vineyard on a very fertile hill… and now I will tell you what I will do to my vineyard. I will remove its hedge, and it shall be devoured; I will break down its wall, and it shall be trampled down. I will make it a waste; it shall not be pruned or hoed, and briers and thorns shall grow up; I will also command the clouds that they rain no rain upon it. For the vineyard of the LORD of hosts is the house of Israel, and the men of Judah are his pleasant planting; and he looked for justice, but behold, bloodshed; for righteousness" (Is. 5:1, 5-7)
