Matthew Henry Presbyterian @wholebiblehenry

Here is, 1. A necessary caution against entertaining any favourable thoughts of prospering profaneness: "Let not thy heart envy sinners; do not grudge them either the liberty they take to sin or the success they are to be pitied rather than envied. Their prosperity is their portion (Psa 73:3), nay, it is their poison," Pro 1:32.

John Gill Reformed Baptist @doctorgill

Let not thine heart envy sinners,.... Their present prosperity and happiness, the pleasure, profit, and honour, they seem to enjoy; all which is but a shadow, fading had temporary; and yet good men are apt to envy it in their hearts, if they do not express it with their lips; and are ready to murmur and think it hard that they should be in straitened...

(Compare Margin). The prosperity of the wicked is short.
