Rashi: The officers perished, like this lion, which perishes without food. So they lost their strength from doing extortion. Oved is when the matter itself is lost, like "Ta'isi k'Seh Oved." "U'Vnei Lavi Yiparadu" refers to Dor ha'Flagah, which were scattered from there over the entire land.

Devar Eliyahu (10): Layish is a female lion without children. A Lavi has children. It says Oved (masculine) because it is included with the male. The children will scatter, without parents.

Malbim: The female lion dies of hunger, and the children scatter. The Nimshal is, when an evil tyrant gets weak, he dies of hunger, and his children seek food. A Tzadik is unlike this. Even if he lacks sometimes, he does not perish - "Od Yenuvun b'Seivah", "Lo Yar'iv Hashem Nefesh Tzadik."
