Job 39:13-16

13"The wings of the ostrich wave proudly, but are they the pinions and plumage of love?

14For she leaves her eggs to the earth and lets them be warmed on the ground,

15forgetting that a foot may crush them and that the wild beast may trample them.

16She deals cruelly with her young, as if they were not hers; though her labor be in vain, yet she has no fear,
