Jealousy is infectious and defiles many before running its course. Jealousy will separate the closest bond and make way for alienation that leads to anger and even murder. Jealousy will evoke hatred and divisive obsession to undermine the other party. Combined with a spirit of religion, jealousy becomes an onslaught filled with the fury of hell itself. The ostrich is a good illustration in nature of how jealousy behaves.
Ostriches are notoriously bad tempered.
A powerful kick from their leg can kill a man. Jealousy brings blindness and gives birth to cruelty. The stones of the sanctuary are scattered at the head of every street. The ostrich epitomizes Jesus' parable of the mote and speck. For with the same measure that ye mete withal it shall be measured to you again.
