"A Psalm of David. Deliver me, O Lord, from the evil man; preserve me from the violent man; Solomon said (Proverbs 4:6), 'Do not forsake wisdom, and she will keep you.' (Proverbs 6:22) 'When you walk, they will lead you; when you lie down, they will watch over you.' So said the Lord to David, 'It is your desire that I preserve you; I will preserve you and keep you in the Torah,' as it says (Proverbs 4:13), 'Keep her, for she is your life.'
Your desire is that I rescue you from the hand of the wicked; sing for joy before Me, and I will deliver you.' (Psalm 32:7) 'Sing for joy, O daughter of Zion; shout aloud, O Israel! Be glad and rejoice with all your heart, O daughter of Jerusalem!' Deliver me, O Lord, from the evil man; who is he, but Esau the wicked? And what is his evil?
Death. So said the Lord, 'When I redeem you from the hand of death, I will redeem you,' as it says (Hosea 13:14), 'I will ransom them from the power of the grave; I will redeem them from death.' Death is the evil that Esau has done. Therefore it is said, 'Deliver me, O Lord, from the evil man,' (Psalm 140:1) and Jacob also said, 'Deliver me, O Lord, from the evil man.' (Genesis 32:12) 'And what kind of evil is it that a violent person does?
Protect me from the hand of the oppressor.' And what was the oppression? (Genesis 32:14-15) 'He spent the night there, and from what he had with him he took a present for his brother Esau: two hundred female goats and twenty male goats, two hundred ewes and twenty rams.' This was not oppression. And so it says (Obadiah 1:10), 'Because of the violence done to your brother Jacob, shame shall cover you.'"
Israel said, "The mountains will be cut off forever, and whatever was swallowed up will be swallowed up." Then the Lord said, "I will bring them out from between their teeth," as it is written (Psalm 68:23), "God said, 'I will bring them back from Bashan.'" Therefore, it is said, "Protect me from the hands of the wicked, who have thought evil thoughts in their hearts," etc. What does it mean to have evil thoughts in the heart?
It does not mean that it is only hidden in one's heart and not spoken aloud. Rather, it means that one thinks evil thoughts in the heart. When they think of evil, they are not only thinking of themselves but also of others, as it is written (Obadiah 1:18), "The house of Jacob will be a fire," etc. This is also expressed in Daniel 7:7-8, "I looked at these horns and there was another horn, a little one, coming up among them, and it uprooted three of the horns with eyes like the eyes of a man, and a mouth uttering great boasts."
Looking at God, one speaks harsh and reviling words. It is written (Daniel 7:11), "I watched until the beast was slain and its body destroyed and thrown into the blazing fire."
