The answer
In the Old Testament, those who took the vow of Nazirite were not allowed to drink wine or eat grapes. "Speak to the children of Israel, and say to them: 'When either a man or woman consecrates an offering to take the vow of a Nazirite, to separate himself to the Lord, 'he shall separate himself from wine and similar drink; he shall drink neither vinegar made from wine nor vinegar made from similar drink; neither shall he drink any grape juice, nor eat fresh grapes or raisins" (Num 6:2-3).Answered by His Eminence Metropolitan Youssef (opens in a new tab)
