It came to pass that he was praying in a certain place.

It came to pass that he was praying in a certain place. When he stopped, one of his disciples asked him to teach them to pray as John taught his disciples. Therefore he for the second time prescribeed to them the Lord's prayer. He used arguments also to stir them up to constancy in prayer and for obtaining the confirmation of their faith. (LUK 11:1-13)
