Answer: Go, teach Eternal Wisdom how to rule

Explanation:

Iambic pentameter is a type of metric very much employed by Shakespeare. One iamb consists of two syllables, an unstressed one followed by a stressed one. If it's a pentameter, it means we have five iambs. The pattern of unstressed and stressed syllables is what determines the rhythm with which the lines should be read. We can see such rhythm - the iambic pentameter one - in the following line (the stressed syllables are in bold):

Go, teach Eternal Wisdom how to rule
