Know yee not that the vnrighteous ſhall not inherite the kingdome of God? Be not deceiued: neither fornicatours, nor idolaters, nor adulterers, nor effeminate, nor abuſers of themſelues with mankinde, Nor theeues, nor couetous, nor drunkards, nor reuilers, nor extortioners, ſhall inherit the kingdom of God.
