Judges 19:17

And when he had lifted up his eyes, he saw a wayfaring man in the street of the city: and the old man said, Whither goest thou? and whence comest thou?

Cross-reference

Genesis 16:8 has the angel ask Hagar the exact same question: 'Whence comest thou? and whither goest thou?' — a direct verbal parallel.

Genesis 19:2 shows Lot inviting strangers to stay — a parallel hospitality scene where the host first sees the travelers, similar to the old man's inquiry.
