Definition

A substance used for cleansing, especially a type of alkali derived from plants (vegetable lye, potash), commonly employed as a soap or detergent; also used as a flux for refining metals. The word denotes both the material itself and metaphorically, the act or condition of cleansing or purifying, especially in ritual or moral contexts.

Semantic Range

alkali, potash, vegetable lye, soap for washing, cleanser for garments, flux for refining metals, metaphor for cleansing or spiritual purification

Root / Etymology

From the root בָּרַר (b-r-r), meaning 'to purify, cleanse, select, make clear.' The noun בֹּר derives from this root, designating a material used specifically for washing or purifying in a physical sense, and, by extension, invoking the concept of purity or cleansing in broader metaphoric usage. Not related to the similar-looking word בּוֹר ('pit, cistern') despite spelling resemblance; compare root meanings and contextual uses.

Historical & Contextual Notes

בֹּר appears infrequently, notably in Malachi 3:2 and Jeremiah 2:22, always in contexts concerning cleansing or purification. In the monarchic and post-exilic periods, it denoted a common substance for washing clothes or purifying metals, in line with the broader ancient Near Eastern use of vegetable-based alkalis (such as potash from burning plants). Early translations occasionally rendered בֹּר as 'soap' or 'lye,' but these terms can be somewhat anachronistic, as ancient cleansers often differed from modern soaps in composition. In Jeremiah 2:22, בֹּר is contrasted with נֶתֶר (nether, natron), another cleansing agent, highlighting different cleaning substances available in the ancient world. The idiomatic use ('never so, purely' in Strong's gloss) does not reflect a separate lexical meaning but stems from the metaphorical association with purity or cleansing. English translations typically use 'lye,' 'soap,' or 'alkali,' but this may obscure the specific source material (ash-derived potash). No connection with later religious terminology; interpretive traditions that use 'soaps' or ritual purity must be understood in their historical context.

Original Strong's Gloss (1890)

the same as בֹּר; vegetable lye (from its cleansing); used as a soap forwashing, or a flux formetals; [idiom] never so, purely.
