Know my way around your ring
No matter how many pounds you bring

from Jay Z – Breathe Easy (Lyrical Exercise) Lyrics on Rap Genius

Meaning

Expanding the Felix Trinidad reference, “pounds” here refers to both to the body weight of an opponent and the scale weight of illegal street drugs

“Ring” refers to a boxing ring as well as possibly your jewelry and/or your drug ring, which Jay is expert at stealing/infiltrating

This could also mean pounds as in the four pound, a term commonly used for the Desert Eagle handgun.
