Trifles, light as air
Are to the jealous confirmations strong,
As proofs of holy writ.—Shakespeare.
Nor Jealousy
Was understood, the injur'd lover's hell.—Milton.
O, beware, my lord, of jealousy;
It is the green-eyed monster which doth mock
The meat it feeds on.—Shakespeare.
1. Definition.—Jealousy is an accidental passion, for which the faculty indeed is unborn. In its nobler form and in its nobler motives it arises from love, and in its lower form it arises from the deepest and darkest Pit of Satan.
