Though - (literally, “when”) he (shall) be fruitful among his brethren Fruitfulness was God’s promise to Ephraim, and was expressed in his name. It was fulfilled, abused, and, in the height of its fulfillment, was taken away. Ephraim is pictured as a fair and fruitful tree. An “East wind,” so desolating in the East, and that, no chance wind, but “the wind of the Lord,” a wind, sent by God and endued by God with the power to destroy, “shall come up from the wilderness,” parching, scorching, fiery, from the burning sands of “Arabia the desert,” from which it came, “and shall dry up the fountain” of his being. Deep were the roots of this fair and flourishing tree, great its vigor, ample and perpetual the fountain of its waters, over which it grew and by which it was sustained. He calls it “‘his’ spring, ‘his’ fountain,” as though this source of its life were made over to it, and made its own. It “was planted by the water side;” but it was not of God’s planting. “The East wind from the Lord” should dry up the deepest well-spring of its waters, and the tree should wither. Such are ungodly greatness and prosperity. While they are fairest in show, their life-fountains are drying up.
He shall spoil the treasure of all pleasant vessels - He, emphatically, the enemy whom the prophet had ever in his mind, as the instrument of God’s chastisement on His people, and who was represented by the East wind; the Assyrian, who came from the East, to whom, as to the East Wind, the whole country between lay open, for the whirlwinds of his armies to sweep over in one straight course from the seat of his dominion.
