“And the multitude rebuked them, because they should hold their peace: but they cried the more, saying, Have mercy on us, O Lord, thou Son of David.”
King James Version (KJV)
20:31 The multitude charged them to hold their peace - And so they will all who begin to cry after the Son of David. But let those who feel their need of him cry the more; otherwise they will come short of a cure.
Mt 20:31 Have mercy on us, O Lord, [thou] Son of David. This was virtually acknowledging Jesus as the Christ, who was to be the Son of David.
