3 verses in the King James Version. Word study for “lest” →
And this I say, lest any man should beguile you with enticing words.
Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ.
Fathers, provoke not your children to anger , lest they be discouraged.
