After Jacob had deceived his father, in procuring for himself the blessing which was intended for his elder brother, Isaac comforts Esau by the prophecy that, although he must serve his brother, yet "it shall come to pass when thou shalt have the dominion, that thou shalt break his yoke from off thy neck." Again, in the next passage where the yoke is mentioned, namely, Lev. xxvi. 13, the word is employed in the metaphorical sense: "I am the Lord your God, which brought you forth out of the land of Egypt, that ye should not be their bondmen, and I have broken the bands of your yoke, and made you go upright." Then, in Deut. xxviii. 48, the word yoke is not only used metaphorically, but with an addition that forcibly expresses its weight and galling character: "Therefore shalt thou serve thine enemies, which the Lord shall send against thee, in hunger, and in thirst, and in nakedness, and in want of all things, and He shall put a yoke of iron upon thy neck, until He have destroyed thee." The word yoke is also used as a metaphor for servitude, even of a domestic character, as we may see in 1 Tim. vi. 1: "Let as many servants as are under the yoke count their own masters worthy of all honour." In the Acts of the Apostles, we find St. Peter using the same metaphor: "Why tempt ye God, to put a yoke on the neck of the disciples, which neither our fathers nor we were able to bear?" And the Lord Himself uses the same metaphor in the well-known passage, "Take my yoke upon you, for my yoke is easy and my burden light." The plough was equally simple, and consisted essentially of a bent branch, one end of which was armed with an iron point by way of a share, while the other formed the pole or beam, and was fastened to the middle of the yoke. It was guided by a handle, which was usually a smaller branch that grew from the principal one. A nearly similar instrument is used in Asia Minor to the present day, and is a curious relic of the most ancient times of history, for we find on the Egyptian monuments figures of the various agricultural processes, in which the plough is made after this simple manner.
