Matthew 22:9

Into the highways] RV 'the partings of the highways.' More probably it means the places where the roads from the country enter a city, and so by metaphor, Gentile territory (Grimm). So also Euthymius: 'He calls the cities and villages of the Gentiles the outlets of the highways, signifying the forlorn state of the Gentiles.'

To feast the poor was quite common. The Talmud says, 'It was a custom among rich men to invite poor travellers to feasts.'
