Albert Barnes Commentary Judges 13:14

"She may not eat of anything that cometh of the vine, neither let her drink wine or strong drink, nor eat any unclean thing; all that I commanded her let her observe." — Judges 13:14 (ASV)

Compare Numbers 6:4. In both passages the vine is described by the somewhat unusual though more accurate term, “vine of the wine”—the grape-bearing vine—to distinguish it from the wild cucumber vine (2 Kings 4:39), or other plants to which the name vine was applied.
