All things come alike to all: there is one event to the righteous, and to the wicked; to the good and to the clean, and to the unclean; to him that sacrificeth, and to him that sacrificeth not: as is the good, so is the sinner; and he that sweareth, as he that feareth an oath.
All things come alike to all - not universally; but as to death. He repeats the sentiment already implied in Ecclesiastes 2:14; Ecclesiastes 3:20; Ecclesiastes 8:14. One event to the righteous, and to the wicked - not eternally; but death is common to all.
The good - morally.
The clean - ceremonially.
To him that sacrificeth, and to him that sacrificeth not - alike to Josiah, who sacrificed to God, and to Ahab, who made sacrifice to Him cease.
He that sweareth - rashly and falsely. Frivolous using of God's holy name is a characteristic mark of the godless.
