Isaiah 41:19

The desert itself shall be transformed into a grove of stately and beautiful trees. I will plant Better: I will place. The shittah treeis the acacia. The myrtleis only mentioned in exilic and post-exilic writings; ch. Isaiah 55:13; Zechariah 1:8; Zechariah 1:10 f.; Nehemiah 8:15.

the oil tree Not the olive, but the oleaster or wild olive.

the fir tree Rather: the cypress (R.V. marg.). With regard to the two last of the seven trees there is no sure tradition. The first (tidhar) is identified by different authorities with the fir, the elm and the plane. The other (tě"asshûr) is according to some the box-tree, according to others a species of cedar, probably the sherbîn-tree of the Arabs (cypressus oxycedrus). The names occur again only in ch. Isaiah 60:13; the last, however, is also disguised in a corrupt reading in Ezekiel 27:6.
