The wilderness and the Arabah will be glad; and the desert will rejoice

These two phrases have basically the same meaning. These places are described as being glad, like a person is glad, because they have received water and are blossoming. Alternate translation: "It will be like the wilderness and the Arabah are glad and the desert will rejoice" (See: rc://en/ta/man/jit/figs-personification and rc://en/ta/man/jit/figs-parallelism)

blossom

This speaks of the plants in the desert blossoming as if the desert itself were blossoming. Alternate translation: "its plants will blossom" (See: rc://en/ta/man/jit/figs-synecdoche)
