A very common tree, which grows in marshy places, Job 40:22Isa 44:4, with a leaf much like that of the olive. God commanded the Hebrews to take branches of the handsomest trees, particularly of the willows of the brook, and to bear them in their hands before the Lord, as a token of rejoicing, at the feast of Tabernacles, Le 23:40.
The "weeping willow," memorable in connection with the mourning Hebrew captives, Ps 137:2, is a native of Babylonica. The "book of the willows," Isa 15:7, on the southern border of Moab, flows into the southeast extremity of the Dead Sea.
