The Hebrew yaen refers to the ostrich, the largest of all birds. The root may suggest speed or greediness. The ostrich appears in poetic and wisdom literature as an image of both strange behavior and raw power.
In Job 39:13-18, God uses the ostrich as an example of His creation's paradoxical design — a creature seemingly devoid of wisdom (abandoning eggs, unmoved by her young's suffering) yet gifted with extraordinary speed that 'scorns the horse and its rider.' The ostrich illustrates God's sovereign freedom in creation — He distributes gifts and seemingly withholds others according to His purposes, not human logic. In Lamentations 4:3, heartless mothers are compared to ostriches, heightening the horror of Jerusalem's suffering. Isaiah 43:20 includes ostriches among the wild animals that honor God, pointing to the creational scope of God's redemption.
