Proverbs 24:1-2

Be not thou envious, &c. The proneness of good men, especially while they are weak, and only in the beginnings of their course of piety and virtue, to be dejected at the prosperity of the ungodly, and so to be tempted to imitate them, is the reason that the admonition which we here meet with is so often repeated; neither desire to be with them Desire not their company, nor to imitate their manner of life. For their heart studieth destruction How they may oppress and destroy others, which yet, at last, fails upon their own heads.
