Salix Babylonica
Supposed to be the Salix Babylonica. Its boughs were used at the Feast of Tabernacles, a season of joy; but at the captivity and since, it is a symbol of sorrow. It was on such that the captives hung their harps when in captivity, of which the Psalmist spoke prophetically (Lev. 23:40; Job 40:22; Psa. 137:2; Isa. 15:7; Isa. 44:4). In Ezekiel 17:5 thy word is tsaphtsaphah, supposed by some to be the Arabic safsaf, a willow or osier which grows by the water.
