Thou shalt answere them, Thus sayeth the Lord God, Behold, I wil take the tree of Ioseph, which is in the hande of Ephraim, and the tribes of Israel his fellowes, and will put them with him, euen with the tree of Iudah, and make them one tree, and they shalbe one in mine hand.
Ezekiel 37:17 And thou shalt ioyne the one to another into one tree, and they shalbe as one in thine hand.
Ezekiel 37:18 And when the children of thy people shall speake vnto thee, saying, Wilt thou not shewe vs what thou meanest by these?
Ezekiel 37:19 Thou shalt answere them, Thus sayeth the Lord God, Behold, I wil take the tree of Ioseph, which is in the hande of Ephraim, and the tribes of Israel his fellowes, and will put them with him, euen with the tree of Iudah, and make them one tree, and they shalbe one in mine hand.
Ezekiel 37:20 And the pieces of wood, whereon thou writest, shalbe in thine hand, in their sight.
Ezekiel 37:21 And say vnto them, Thus saith the Lord God, Beholde, I will take the children of Israel from among the heathen, whither they be gone, and wil gather them on euery side, and bring them into their owne land.
The verse centers on "thou", "shalt", "answere", "thus", "sayeth", "lord", "behold", and "take". 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 18's "And when the children of thy people..." into verse 20's "And the pieces of wood whereon thou...", so "thou" and "shalt" belong inside that flow. In Ezekiel 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.
