'Have Mercy' in the Bible

‘Father Abraham!’ he called out, ‘Have mercy on me and send Lazarus to dip the tip of his finger in water and cool my tongue, because I am in agony in this flame!’

and raised their voices, saying, “Jesus, Master, have mercy on us!”

So he called out, “Jesus, Son of David, have mercy on me!”

Then those in front told him to keep quiet, but he kept crying out all the more, “Son of David, have mercy on me!”
