Cab (Biblical)

In the Bible, a cab is an ancient Hebrew unit of dry measurement, primarily used for grains and other dry commodities. It is mentioned specifically in 2 Kings 6:25 during the account of the severe famine in Samaria, where “the fourth part of a cab of dove’s dung” was sold for a high price, illustrating the desperation and scarcity of the time. A cab is estimated to be approximately 1.2 liters (or about 1.1 quarts), though exact conversions vary due to historical uncertainties. The term is not commonly found outside of this passage, making it one of the lesser-known biblical units. Its mention provides insight into the economic and social distress during sieges in ancient Israel. Understanding such units helps readers better grasp the historical and cultural context of biblical narratives, especially when interpreting descriptions of famine, trade, and daily life in the Old Testament.
