Yoke

+ A well-known implement of husbandry, frequently used metaphorically for subjection, e.g. (1 Kings 12:4,9-11; Isaiah 9:4; Jeremiah 5:5) hence an "iron yoke" represents an unusually galling bondage. (28:48; Jeremiah 28:13)

+ A pair of oxen, so termed as being yoked together. (1 Samuel 11:7; 1 Kings 19:19,21) The Hebrew term is also applied to asses, (Judges 19:10) and mules, (2 Kings 5:17) and even to a couple of riders. (Isaiah 21:7)

+ The term is also applied to a certain amount of land, (1 Samuel 14:14) equivalent to that which a couple of oxen could plough in a day, (Isaiah 5:10) (Authorized Version "acre"), corresponding to the Latin jugum .
