Rashi, on Ps 11:9

“The wicked walk round about: according to thy highness, thou best multiplied the children of men.”

“Wicked men walk on all sides to hide traps to cause me to stumble. when the basest to the sons of men is elevated Heb. כרם זלות לבני אדם [They walk on all sides] because of their envy, for they are jealous of my greatness, that I was taken from behind the sheep to be a king. This is the interpretation of כרם זלות לבני אדם: when a man considered by the sons of men to be base is elevated. This is on the order of the passage elsewhere (below 118:22): “The stone that the builders rejected became a cornerstone.” The Midrash Aggadah interprets it concerning Israel in the future, when they will be elevated. [Unknown Midrashic source] Menachem interprets כרם זלות לבני אדם (pp. 78, 164): like a gluttonous wild ox to devour the sons of men. Accordingly, כרם is rendered: like a רים or ראם, and זלות is like (Deut. 21:20) זולל וסבא, “a glutton and a drunkard.” The following is its interpretation: The wicked walk on all sides around the poor man; the wicked walk to swallow him for naught, as a wild ox to swallow the sons of men.”
