The words of King Lemuel.
v.1 The words of King Lemuel. An oracle that his mother taught him. No one knows who King Lemuel was or where he was king. “An oracle” could be rendered “of Massa” as in 30:1. v.2-9 provide instruction on what the ideal human king should look like.
v.2-3 What are you doing my son? (The repetition of son indicates the seriousness.) Do not waste your strength on women and on those who destroy kings. Perhaps the idea is that having many women saps his strength to rule well.
v.4-5 Kings should not be given to strong drink (20:1). It clouds their judgment and interferes with their role as protector of the afflicted. They will forget their laws and pervert justice.
v.6-7 Give strong drink to the one who is perishing and those in bitter distress; that they remember their misery no more.
v.8-9 Judge righteously, protecting the rights of the poor and needy and all who are destitute. Speak for the one who is mute and unable to speak for himself.
