A.T. Robertson Commentary Luke 4:26

"and unto none of them was Elijah sent, but only to Zarephath, in the land of Sidon, unto a woman that was a widow." — Luke 4:26 (ASV)

Unto Zarephath (εις Σαρεπτα). The modern village Surafend on the coast road between Tyre and Sidon.

Unto a woman that was a widow (προς γυναικα χηραν). Literally, unto a woman a widow (like our vernacular widow woman). This is an illustration of the proverb from the life of Elijah (1 Kings 17:8,9). This woman was in the land of Sidon or Phoenicia, a heathen, where Jesus himself will go later.
