One example of dramatic irony comes when the old soothsayer visits the King. Oedipus ridicules the man because he's blind, and Tiresias in a fit of anger tells the king that though he can see he is "blind" to the truth. When Oedipus becomes blind, he finally realizes the truth of the man's words. Irony is also to be found in the fact that it is the blind man who truly sees.
Oedipus confesses what really happens. Oedipus said that he lashed out in rage, because the driver of Lauis's charriage forced him off the road or tried to and he lashed out and killed thme all but the servant said it was a group of theives, because Oedipus actually killed Lauis. This is ironic, because Oedipus confessed what really happened to Lauis.
You can use the fourth verse. below is an interpretation of the verse.
when we are divided or separated we sorrow or we hurt we shall be joined in heart(maybe not physically but the person that passes forever holds a special place in someone's heart.) but hope to see each other again.
