“Teil tree” is an older English rendering of a Hebrew term referring to the terebinth, or turpentine tree, Pistacia terebinthus. The same Hebrew term is elsewhere rendered “oak,” “trees,” or “elm.”
The term occurs in Isaiah and corresponds to a Hebrew word used in several passages for trees identified in older versions as oaks or elms and in later rendering as terebinths.
The terebinth commonly stood alone rather than in forests, often on hillsides or in bare ravines. It was associated with the terebinth of Mamre, which was said to remain from Abraham’s time until the fourth century.
