Reference: Teil Tree
(an old name for the lime-tree, the tilia), Isa 6:13, the terebinth, or turpentine-tree, the Pistacia terebinthus of botanists. The Hebrew word here used (elah) is rendered oak (q.v.) in Ge 35:4; Jg 6:11,19; Isa 1:29, etc. In Isa 61:3 it is rendered in the plural "trees;" Ho 4:13, "elm" (R.V., "terebinth"). Ho 4:13, "elm" (R.V., "terebinth"). In 1Sa 17:2,19 it is taken as a proper name, "Elah" (R.V. marg., "terebinth").
The terebinth of Mamre, or its lineal successor, remained from the days of Abraham till the fourth century of the Christian era, and on its site Constantine erected a Christian church, the ruins of which still remain.
This tree "is seldom seen in clumps or groves, never in forests, but stands isolated and weird-like in some bare ravine or on a hill-side where nothing else towers above the low brushwood" (Tristram).
The Hebrew word is elah, and is supposed to be the terebinth, though it is often translated 'oak.' In Isa 6:13 'the oak' (allon) is mentioned as well as the elah, different trees are therefore doubtless indicated by the two Hebrew words. It is now generally supposed that allon refers to the oak, and elah to the terebinth, the Pistacia terebinthus.
