Though he is fruitful among his brothers, an east wind will come, The breath of Yahweh coming up from the wilderness; And his spring will become dry, And his fountain will be dried up. He will plunder the storehouse of treasure.
*Dr. Henderson and others render  baqaq "luxuriant," and argue that the idea of emptying, which the verb also has (derived) from that  of pouring out entirely  or  abundantly  the contents of a vessel, does not suit the present connection. But there is no need for the smallest violence. For inasmuch as the sense is clearly a vine that is luxuriant in everything but fruit, pouring out, as it literally means, its wood and leaves, the authorized version is justified, not those who overlook the connection, and take it in the sense of fruitfulness. The Targum of Jonathan is decidedly in favour of this; the old versions are divided, like the moderns.
