Why does it say "Yorucha" and "Yomeru Lach"?
1.
Devar Eliyahu: Yorucha what they received; Yomeru Lach from their own understanding.
2)
What do we learn from "umi'Libam Yotzi Milim"?
1.
Devar Eliyahu: This is what they know from investigation over time. This is like "Zechor Yemos Olam Binu Shnos Dor va'Dor" - Zechor is investigation over time; Binu is their own understanding. "She'al Avicha v'Yagedecha" is tradition. The three correspond to Chochmah, Binah and Da'as.
2.
Malbim: Aside from their tradition, they invent a Mashal from vegetation to teach to you.
