Why does it say "Yaldah v'Azov"?
1.
Rashi: It abandoned 1 its baby to seek pasture. Radak - pasture (grass) is scarce, so it went to another land to seek it. It was not concerned for its baby, even though it is merciful, and went to keep itself alive.

Radak: Azov is Makor (infinitive) in place of the past tense. It is as if it says v'Azvah. Also "veha'Chayos Ratzo va'Shov" (Yechezkel 1:14) is like Ratzu v'Shavu.
