Head and tail, branch and rush; i.e. the whole nation, from the highest to the lowest. The "branch" intended is the "palm branch," at once lofty in position and the most glorious form of vegetable life (Psalms 92:12; So Psalms 7:7, Psalms 7:8, etc.
); the "rush" is the simple "sedge" that grows, not only low on the ground, but in the "mire" (Job 8:11). The same expression occurs again in Isaiah 19:15.
