The meaning of Pine tree in the Bible
(From Easton's Bible Dictionary)

Heb. tidhar, mentioned along with the fir-tree in Isaiah 41:19; 60:13. This is probably the cypress; or it may be the stone-pine, which is common on the northern slopes of Lebanon. Some suppose that the elm, others that the oak, or holm, or ilex, is meant by the Hebrew word. In Nehemiah 8:15 the Revised Version has "wild olive" instead of "pine." (See FIR .)
