Upon this unmitigated wilderness, where life is reduced to poverty and danger; where nature starves the imagination, but excites the faculties of perception and curiosity; with the mountain tops and the sunrise in his face, but above all with Jerusalem so near,--Amos did the work which made him a man, heard the voice of God calling him to be a prophet, and gathered those symbols and figures in which his prophet's message still reaches us with so fresh and so austere an air. Amos was _among the shepherds of Tekoa_. The word for _shepherd_ is unusual, and means the herdsman of a peculiar breed of desert sheep, still under the same name prized in Arabia for the excellence of their wool.[134] And he was _a dresser of sycomores_. The tree, which is not our sycamore, is very easily grown in sandy soil with a little water. It reaches a great height and mass of foliage. The fruit is like a small fig, with a sweet but watery taste, and is eaten only by the poor. Born not of the fresh twigs, but of the trunk and older branches, the sluggish lumps are provoked to ripen by pinching or bruising, which seems to be the literal meaning of the term that Amos uses of himself--_a pincher of sycomores_.[135] The sycomore does not grow at so high a level as Tekoa;[136] and this fact, taken along with the limitation of the ministry of Amos to the Northern Kingdom, has been held to prove that he was originally an Ephraimite, a sycomore-dresser, who had migrated and settled down, as the peculiar phrase of the title says, _among the shepherds of Tekoa_.[137] We shall presently see, however, that his familiarity with life in Northern Israel may easily have been won in other ways than through citizenship in that kingdom; while the very general nature of the definition, _among the shepherds of Tekoa_, does not oblige us to place either him or his sycomores so high as the village itself. The most easterly township of Judæa, Tekoa commanded the whole of the wilderness beyond, to which indeed it gave its name, _the wilderness of Tekoa_. The shepherds of Tekoa were therefore, in all probability, scattered across the whole region down to the oases on the coast of the Dead Sea, which have generally been owned by one or other of the settled communities in the hill-country above, and may at that time have belonged to Tekoa, just as in Crusading times they belonged to the monks of Hebron, or are to-day cultivated by the Rushaideh Arabs, who pitch their camps not far from Tekoa itself. As you will still find everywhere on the borders of the Syrian desert shepherds nourishing a few fruit-trees round the chief well of their pasture, in order to vary their milk diet, so in some low oasis in the wilderness of Judæa Amos cultivated the poorest, but the most easily grown of fruits, the sycomore.[138] All this pushes Amos and his dwarf sheep deeper into the desert, and emphasises what has been said above, and still remains to be illustrated, of the
