To appoint ... to give - The double verb, with the one and the same accusative, imparts glowing vehemence to the style.
beauty for ashes - There is a play on the sound and meaning of the Hebrew words, peer, epher, literally, “ornamental headdress” or tiara (Eze 24:17), worn in times of joy, instead of a headdress of “ashes,” cast on the head in mourning (2Sa 13:19).
oil of joy - Perfumed ointment was poured on the guests at joyous feasts (Psa 23:5; Psa 45:7, Psa 45:8; Amo 6:6). On occasions of grief its use was laid aside (2Sa 14:2).
garment of praise - bright-colored garments, indicative of thankfulness, instead of those that indicate despondency, as sackcloth (Joh 16:20).
trees of righteousness - Hebrew, terebinth trees; symbolical of men strong in righteousness, instead of being, as heretofore, bowed down as a reed with sin and calamity (Isa 1:29, Isa 1:30; Isa 42:3; 1Ki 14:15; Psa 1:3; Psa 92:12-14; Jer 17:8).
