Judges 19:17

‘ And he lifted up his eyes, and saw the wayfaring man in the city square, and the old man said, ‘Where are you going to, and where have you come from?'

Lifting up the eyes is merely a phrase indicating ‘turning the attention on'. On doing this he saw the wayfaring man in the street of the city, whom he realised to be a traveller by the fact of his two asses and his companions, and by their general behaviour. So he asked where they had come from and what their destination was.
