XX A well-known implement of husbandry, frequently used metaphorically for subjection , e.g. ( 1 Kings 12:4 1 Kings 12:9-11 ; 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 1 Kings 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 .
