Verse 22. I hate them with perfect hatred. He does not leave it a matter of question. He does not occupy a neutral position. His hatred to bad, vicious, blasphemous men is intense, complete, energetic. He is as whole hearted in his hate of wickedness as in his love of goodness.
I count them mine enemies. He makes a personal matter of it. They may have done him no ill, but if they are doing despite to God, to his laws, and to the great principles of truth and righteousness, David proclaims war against them. Wickedness passes men into favour with unrighteous spirits; but it excludes them from the communion of the just. We pull up the drawbridge and man the walls when a man of Belial goes by our castle. His character is a casus belli; we cannot do otherwise than contend with those who contend with God.
EXPLANATORY NOTES AND QUAINT SAYINGS
Verse 22. I hate them with perfect hatred. What is "with a perfect hatred"? I hated in them their iniquities, I loved thy creation. This it is to hate with a perfect hatred, that neither on account of the vices thou hate the men, nor on account of the men love the vices. For see what he addeth, "They became my enemies." Not only as God's enemies, but as his own too doth he now describe them. How then will he fulfil in them both his own saying, "Have not I hated those that hated thee, Lord", and the Lord's command, "Love your enemies"? How will he fulfil this, save with that perfect hatred, that he hate in them that they are wicked, and love that they are men? For in the time even of the Old Testament, when the carnal people was restrained by visible punishments, how did Moses, the servant of God, who by understanding belonged to the New Testament, how did he hate sinners when he prayed for them, or how did he not hate them when he slew them, save that he "hated them with a perfect hatred"? For with such perfection did he hate the iniquity which he punished, as to love the manhood for which he prayed. --Augustine.
