House of mourning ... house of mirth - These phrases acquire a forcible significance from the Eastern custom of prolonging both festive and mournful celebrations through several days. See Genesis 50:10; Judges 14:17. This verse indicates that a life of enjoyment, does not mean the abandonment of ourselves to pleasures, but the thankful and sober use of the beautiful things which God gives us.
