Charles Ellicott Commentary Judges 13:4

"Now therefore beware, I pray thee, and drink no wine nor strong drink, and eat not any unclean thing:" — Judges 13:4 (ASV)

Drink not wine. —The mother is to share for a time in part of the Nazarite vow.

Strong drink. — Sheekar (Septuagint, Sikera) means intoxicating liquor not made from grapes (Luke 1:15).

Eat not any unclean thing. — (Leviticus 11:0). The law applied to all Israelites, but is to be specially observed by the wife of Manoah, to impress on her and on the nation the separated character of her son.
