And thou shalt build un altar to the Lord thy God, in the top of this rock, whereupon thou didst lay the sacrifice before: and thou shalt take the second bullock, and shalt offer a holocaust upon a pile of the wood, which thou shalt cut down out of the grove.
Judges 6:24 And Gedeon built there an altar to the Lord, and called it the Lord's peace, until this present day. And when he was yet in Ephra, which is of the family of Ezri,
Judges 6:25 That night the Lord said to him: Take a bullock of thy father's, and another bullock of seven years, and thou shalt destroy the altar of Baal, which is thy father's: and cut down the grove that is about the altar:
Judges 6:26 And thou shalt build un altar to the Lord thy God, in the top of this rock, whereupon thou didst lay the sacrifice before: and thou shalt take the second bullock, and shalt offer a holocaust upon a pile of the wood, which thou shalt cut down out of the grove.
Judges 6:27 Then Gedeon, taking ten men of his servants, did as the Lord had commanded him. But fearing his father's house, and the men of that city, he would not do it by day, but did all by night.
Judges 6:28 And when the men of that town were risen in the morning, they saw the altar of Baal destroyed, and the grove cut down, and the second bullock laid upon the altar, which then was built.
The verse centers on "thou", "shalt", "build", "altar", "lord", "rock", and "whereupon". It is saying that the verse draws attention to "thou" and "shalt", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 25's "That night the Lord said to him..." into verse 27's "Then Gedeon taking ten men of his...", so "thou" and "shalt" belong inside that flow. In Judges context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "thou" and "shalt" with trust shaped by these words, not by a vague optimism outside the passage.
