This morning in church the preacher said, 'The devil doesn't play fair. He's sleekit.' The first part of that statement is a common one that appears in sermons around the world but the second part will probably only be heard in this part of the world, either in Scotland or Ulster.
The word sleekit, is a Scots and Ulster-Scots word that means 'sly, cunning, deceitful' and that is true of Satan. In Ephesians 6:11 the Bible speaks about 'the wiles of the devil'.
