God defend me from that Welsh fairy,Lest he transform me to a piece of cheese!

Now I perceive the devil understands Welsh.

But then I sigh; and, with a piece of Scripture, Tell them that God bids us do good for evil: And thus I clothe my naked villany With odd old ends stol'n forth of holy writ; And seem a saint when most I play the devil

Mind your speech a little lest you should mar your fortunes.

Angels and ministers of grace defend us!

I think the devil will not have [you] damned, lest the oil that's in [you] should set hell on fire.
