Though he be fruitful among his brethren. It should rather be, for he bear fruit among brethren. כִּי, in this verse, is neither a particle of time, "when," nor a conditional particle, "if," but "for," adducing "a reason to prove that the promised grace of redemption would certainly stand firm."
Ki is distinguished from אִם by being "only used in cases where a circumstance is assumed to be real For one that is merely supposed to be pebble, אִם is required," as may be inferred from the interchange of the two words in Numbers 5:19 and Numbers 5:20.
The name Ephraim, signifying "double-fruitfulness," shall be verified, confirming the promised redemption from death, and, by the pledge of blessing, which the name implies affording a guarantee that the coming storm would not quite overwhelm them.
The play on the name Ephraim fixes the meaning of יַפְרִיא, the aleph taking the place of he. The Septuagint διαστελεῖ, equivalent to "shall cause a division," and Jerome's divider, suppose יַפְרִיד or יַפְלִיא.
But though fruitful among the other tribes, yet the abuse of that fruitfulness invited the instrument of destruction. There is an allusion to the patriarchal blessing, "Joseph is a fruitful bough by a well;" the source of his fruitfulness was that well or fountain; while the drying up of it would be the certain cause of barrenness.
An east wind shall come, the wind of the Lord shall come up from the wilderness. Thus, while Ephraim presents the pleasing picture of a fair and fruitful tree, the element of destruction is already on the way.
A wind, the east wind, with its rude vehemence, blighting heat, and desolating effect, was coming. It was a wind, not coming by chance, but commissioned by Jehovah as a minister of vengeance to execute his wrath.
It was, moreover, a wind issuing forth from its home in the desert, and fraught with fiery heat from the scorching sands of the Arabian desert. And his spring shall become dry, and his fountain shall be dried up.
This flourishing tree, planted by the living spring, to which it owed its vigor and verdure, was doomed soon to wither in consequence of the drying up of the waters, that nourished it, by the east wind.
He shall spoil the treasure of all pleasant vessels. Here the figure merges in the fact. The Assyrian conqueror was the blustering east wind, that swept like a whirlwind with his armies from the east.
He not only ravaged the country, but rifled the treasures of the capital The keli chemdah included all the valuables and treasures of Samaria referred to in the following verse. Kimchi explains the verse as follows: "For Ephraim was fruitful among brethren as long as he did not make calves.
He became increasingly great and fruitful among his brethren, as Jacob said of him.... And now that he has sinned, an east wind of the Lord shall come; and it is the King of Assyria that is meant. And he compares him to the east wind, because it is a wind from the east, for the land of Assyria lies to the east of the land of Israel; and further he says, 'east wind,' because it is a violent wind.
And he says, 'wind of Jehovah,' to magnify the wind and emphasize it; and he says also, 'spirit of Jehovah,' because Jehovah the blessed stirred up his spirit (i.e. spirit of the King of Assyria) to come against Israel, 'goeth up from the wilderness;' wind is always in the wilderness.
Or the explanation is, because the wilderness is between the land of Israel and the land of Assyria; and before this wind, which is the King of Assyria, is dried up the fountain of Ephraim, which was at first like a tree flourishing by the waters."
And now before this wind shall its spring become dry and its fountain dried up. The verb יֵבוֹשׁ, as from בּוֹשׁ, is an irregular formation for הוֹבִישׁ, as on the contrary we find the Hiph. הוֹבִישׁ, as if from יָבֵשׁ.
