When speaking to Manoah, the angel repeats the exact instructions previously given to his wife. These strict guidelines directly mirror the rules and restrictions of a Nazirite [ביאור שטיינזלץ].
The prohibition specifically targets the cultivated vine used for making wine. This distinction ensures it is clearly separated from wild vines that naturally grow in the field and are not used for wine production [מצודת ציון].
Wrapping up the message, the angel makes it clear that he has no new rules to add. He simply reinforces the original command, stressing that Manoah's wife must carefully follow everything she was already told [מצודת דוד, ביאור שטיינזלץ].
