Job 39:13-16

13Gavest thou the goodly wings to the peacocks? or wings and feathers to the ostrich?1 14Which leaveth her eggs in the earth, and warmeth them in the dust, 15And forgetteth that the foot may crush them, or that the wild beast may break them. 16She is hardened against her young ones, as though they were not hers: her labour is in vain without fear;
