'Righteous' in the Bible

I said in my heart, God will judge the righteous and the wicked; for there is a time there for every purpose and for every work.

All this have I seen in the days of my vanity: there is a righteous man that perisheth by his righteousness, and there is a wicked man that prolongeth his days by his wickedness.

Be not righteous overmuch; neither make thyself overwise: why shouldest thou destroy thyself?

Surely there is not a righteous man upon earth, that doeth good and sinneth not.

There is a vanity which is done upon the earth; that there are righteous men unto whom it happeneth according to the work of the wicked; and there are wicked men to whom it happeneth according to the work of the righteous. I said that this also is vanity.

For all this I laid to my heart and indeed to investigate all this, that the righteous, and the wise, and their works, are in the hand of God; man knoweth neither love nor hatred: all is before them.

All things come alike to all: 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; he that sweareth, as he that feareth an oath.
