Albert Barnes Commentary Isaiah 36:17

"until I come and take you away to a land like your own land, a land of grain and new wine, a land of bread and vineyards." — Isaiah 36:17 (ASV)

Until I come – These are the words of the king of Assyria delivered by Rabshakeh. It was proposed that they should remain safely in Jerusalem until Sennacherib himself should come and remove them to his own land. He was now engaged in the siege of Lachish (Isaiah 36:2), and it is probable that he purposed to take some other of the unsubdued towns in that part of Palestine.

And take you away – It was common for conquerors in ancient times to remove a vanquished people from their own country. They did this either by sending them out in colonies to populate some unsettled region, or by removing the main body of them to the land of the conqueror. This was done for various purposes: sometimes to make slaves of them, sometimes for purposes of triumph, but more commonly to secure them from revolt.

In this manner, the ten tribes were removed from the kingdom of Samaria, and thus also the Jews were carried to Babylon. Suetonius says (chapter 21) of Augustus that he removed the Suevi and the Sicambri into Gaul and stationed them on the Rhine. The same thing was also practiced in Egypt, for the purpose of securing the people from revolt (Genesis 47:21).

A land like your own land – This means a fertile land, abounding in the same produce as your own.

And wine – Palestine was celebrated for its vines. The idea is that in the land to which he would remove them, they would not be in need.
