Question

In this excerpt from Richard Lovelace's "To Lucasta Going to the Wars," which lines use iambic trimeter?
Tell me not, Sweet, I am unkind,
That from the nunnery
Of thy chaste breast, and quiet mind
To war and arms I fly.

True, a new mistress now I chase,
The first foe in the field;
And with a stronger faith embrace
A sword, a horse, a shield.
