Acts 7:6-7

And this is, in effect, what God spoke [to him]: That his DESCENDANTS WOULD BE ALIENS (strangers) IN A FOREIGN LAND, AND THAT THEY WOULD BE ENSLAVED AND MISTREATED FOR FOUR HUNDRED YEARS. ‘AND I WILL JUDGE ANY NATION TO WHOM THEY WILL BE IN BONDAGE,’ said God, ‘AND AFTER THAT THEY WILL COME OUT AND SERVE ME [in worship] IN THIS PLACE.’ [Gen 15:13, 14; Ex 3:12]
