Charles Ellicott Commentary Proverbs 14:10

"The heart knoweth its own bitterness; And a stranger doth not intermeddle with its joy." — Proverbs 14:10 (ASV)

The heart knows his own bitterness ... —No one can perfectly sympathize with the sorrows or joys of others, except the ideal Son of Man, who came to bear our griefs and carry our sorrows , yet could join in the marriage feast at Cana.
