If you want to get technical, people would specifically refer to this line as a simile, as it is a type of metaphor; see MC Lyte’s line in Lyte as a Rock for details.

However, what Lupe’s really saying is “I think I like her like I met her ‘fore” (as in, “I met her before”), which is deliberately pronounced like “metaphor” here

That’s some tricky wordplay, but this is Lupe, the undisputed RapGenius™ King of Lyrical Trickiness

Psalm 23 of the Christian Bible states:

Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me; your rod and your staff, they comfort me

“Fresh to def,” and other such variants, are popular phrases all meaning the same thing: “good-looking”.

From her shoes to everything about her is attractive and fly. Set refers to a woman’s entire physical package: facial features, body shape, and style.

There’s no such thing as an honest victory for somebody anymore, in a fight or otherwise, due to the power of the pistol

What a nice list of acceptable things in the hood:
Jewelry, Timberland kicks, rims on cars

Camcorder is the outdated tool used for recording family moments. Dad with a camcorder = classic image:

The social issues they talked about were mirrored in his life.

Ignorant wisdom is questionable, as it’s contradicting, but sort of understandable in rap: philosophy in slang and etc. It could also be referring in this case to “street smarts,” or the type of wisdom that one can achieve without the use of higher education (college, university, etc).

Ja Rule took shots at 50, Dre and Eminem on a diss track entitled “Loose Change” (50 Cent, loose change… get it?). At the very end he spits the lines:

Em, you claim your mother’s a crackhead and Kim is a known slut
So what’s Hailie gon' be when she grows up?

Ja: Good diss, bad career move!

Refers to Lauryn Hill’s song, To Zion where she says.

Now the joy of my world is in Zion"

Zion is the name of her first born son and refers to the Rastafarian code word. The song is about his conception and birth, which occurred despite heavy pressure from music business folks around her to terminate the pregnancy because of possible effects on her career.

‘Ye wishes Lauryn never had a bunch of damn kids and her joy still came from making dope music. She has only released one album, and has been absent for the best part of 15 years.
