Comentario sobre Isaías 29:24

and grumblers shall learn instruction (וְרוֹגְנִים) an expression similar to (Deut. 1:27) “And you grumbled (וַתְּרָגְנוּ) in your tents.” Those who were complaining and grumbling about the words of the prophets shall learn instruction.

ורגנים And they that murmured, comp. יתרגנו and you were murmuring (Deut. 1:27). They are the opposite of those that learn doctrine.
