KJV: Though he be fruitful among his brethren, an east wind shall come, the wind of the LORD shall come up from the wilderness, and his spring shall become dry, and his fountain shall be dried up: he shall spoil the treasure of all pleasant vessels.
NASB: Though he flourishes among the reeds, An east wind will come, The wind of the LORD coming up from the wilderness; And his fountain will become dry And his spring will be dried up; It will plunder his treasury of every precious article.
