In Judges 13:14, the angel repeats the same prohibition, reinforcing its importance for Samson's Nazirite dedication.

Numbers 6:2 defines the Nazirite vow, the institution behind the command here — Samson is to be a lifelong Nazirite.

Numbers 6:3 lists the exact wine and grape prohibitions for Nazirites, which this verse commands for Samson's mother.

Luke 1:15 shows John the Baptist also abstaining from wine from birth, mirroring Samson's Nazirite calling.

Leviticus 11:47 explains the purpose of distinguishing clean from unclean, which underlies the command to eat nothing unclean here.
