Berean Standard Bible
Isaiah 33:19
“You will no longer see the insolent, a people whose speech is unintelligible, who stammer in a language you cannot understand.”

In context
17Your eyes will see the King in His beauty and behold a land that stretches afar.
18Your mind will ponder the former terror: “Where is he who tallies? Where is he who weighs? Where is he who counts the towers?”
19You will no longer see the insolent, a people whose speech is unintelligible, who stammer in a language you cannot understand.
20Look upon Zion, the city of our appointed feasts. Your eyes will see Jerusalem, a peaceful pasture, a tent that does not wander; its tent pegs will not be pulled up, nor will any of its cords be broken.
21But there the Majestic One, our LORD, will be for us a place of rivers and wide canals, where no galley with oars will row, and no majestic vessel will pass.
