Behold, I have made you a new, sharp threshing sledge with double edges; You will thresh the mountains and pulverize them, And will make the hills like chaff.
Behold, I have made you a new, sharp threshing sledge with double edges; You will thresh the mountains and pulverize them, And will make the hills like chaff.
Isaiah 41:13 For I am Yahweh your God, who strongly takes hold of your right hand, Who says to you, ‘Do not fear, I will help you.’
Isaiah 41:14 Do not fear, you worm Jacob, you men of Israel; I will help you,” declares Yahweh, “and your Redeemer is the Holy One of Israel.
Isaiah 41:15 Behold, I have made you a new, sharp threshing sledge with double edges; You will thresh the mountains and pulverize them, And will make the hills like chaff.
Isaiah 41:16 You will winnow them, and the wind will carry them away, And the storm will scatter them; But you will rejoice in Yahweh; You will boast in the Holy One of Israel.
Isaiah 41:17 “The afflicted and needy are seeking water, but there is none, And their tongue is parched with thirst; I, Yahweh, will answer them Myself, As the God of Israel I will not forsake them.
The verse centers on "behold", "sharp", "threshing", "sledge", "double", "edges", and "mountains". It is saying that the verse draws attention to "behold" and "sharp", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "Do not fear you worm Jacob you..." into verse 16's "You will winnow them and the wind...", so "behold" and "sharp" belong inside that flow. In Isaiah context, the local focus is the Holy One of Israel, judgment and restoration, the servant of the LORD, and Zion's hope.
A plain takeaway is to answer the verse's own emphasis on "behold" and "sharp" with trust shaped by these words, not by a vague optimism outside the passage.
