If I be left behind,
A moth of peace, and he go to the war,
The rites for which I love him are bereft me,
And I a heavy interim shall support
By his dear absence. Let me go with him.

– William Shakespeare

Othello, Act 1, Scene 3. Desdemona so loves Othello that she doesn’t want to be separated, even in war. Here she pleads with the Duke and his court to allow her to accompany Othello to Cyprus. In a metaphor she compares herself to a "moth of peace" if she is left behind. This demonstrates Desdemona’s strength of character, But just as moths fly towards light and flame, this also foreshadows how Desdemona is flying towards danger and death.
