I believe that the phrase from Mandela's speech that is an example of a metaphor is the first one - 'the children, [...] the greatest of our treasures."
A metaphor is a type of comparison, where two or more things are compared without using words such as <em>like </em>or <em>as. </em>Here, the children are the greatest of our treasures - they are compared to a treasure, something which is the most important thing of all.

The present perfect verb tense refers to something that was just completed in the recent past. For example, “I have just finished writing my essay.” Present perfect can also be used to describe something that happened in the past but is still occurring. For example, “Daniel has worked for Exxon for the past 12 years.” Past perfect refers to how two things that have already happened relate. For example, “Before he went home from work, Eric stopped by the store.” Future perfect tense refers to something that will be completed before a future time. For example, “I will write my essay before next Friday.”
