Job 39:13-16

13The wing of the ostrich rejoiceth, but are her pinions and feathers kindly?

14For she leaveth her eggs on the earth, and warmeth them in the dust,

15And forgetteth that the foot may crush them, or that the wild beast may trample them.

16She is hardened against her young ones, as if they were not hers: though her labour be in vain, she is without fear;
