Psalm 58 is a community lament, wherein God’s faithful people sing about injustice by their own rulers.
1-2 – The Psalm begins by directly addressing the wicked rulers over them, who allow injustice, wrongs, and violence to the people. Calling the wicked rulers gods is not to say that the wicked rulers are somehow the Nephilim, but rather to mock them because they act like they are gods. Alternatively, some scholars believe that the meaning of the word in Hebrew is not gods but mighty lords.
3-5 – David now brings the charge against these wicked rulers. The common thread is that the wicked rulers do not honor God. They do not fear him, and so they act with impunity. They are compared to poisonous serpents with venom like the adder.
6-9 – A poetic curse is called upon the wicked rulers that their teeth will be broken, that they will dissolve like snails in the sun, that they will be like a still born child, and that they be swept away like brittle thorns in a fire.
10-11 – The faithful are reminded that God will seek vengeance against the wicked rulers, and the faithful will glorify God as righteous. God is the ultimate righteous ruler who will call these petty tyrants to account.
