"No, from Russia. "I izbavi nas ot lukavogo". It is even more personal than "the evil one", it literally means "the crafty one", but is instantly understood as a euphemism for Satan. You certainly would not call pneumonia or a car accident "crafty one", even if one might, at a stretch, say that the accident was an evil one."

Now that's fascinating because the Greek word ponhroV actually means that, The Evil One, but with overtones of slyness, like a fox.

Indeed, the modern Serbian word лукав, лукави (lukav, lukavi) means sly.

This always gives me confidence that Slavonic texts (after all they have been devised by SS Cyrill and Mehtodius who spoke Slavonic as well as Greek), convey the true original Greek meaning and tense.

The etymology of "lukavy" has to do with a bend. E.g. archbow is "luk" and a bend in the river is "luka". The adjective is also used to describe fairly innocent slightly furtive behavior, such as in "sly smile".
