Luke 3:4; Luke 18:7; Luke 18:38

4 As it is written in the book of the words of Esaias the prophet, saying , The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
7 And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?
38 And he cried , saying , Jesus, thou Son of David, have mercy on me.
