“And on the third day after the birth of our Lord Jesus Christ, Mary went out of the cave, and, entering a stable, placed the child in a manger, and an ox and an ass adored him. Then was fulfilled that which was said by the prophet Isaiah, “The ox knows his owner and the ass his master’s crib.” Therefore, the animals, the ox and the ass, with him in their midst incessantly adored him. Then was fulfilled that which was said by Habakkuk the prophet, saying, “Between two animals you are made manifest.”
The ox traditionally represents patience, the nation of Israel, and Old Testament sacrificial worship
The ass represents humility, readiness to serve, and the Gentiles.
