Esias 29:24

24 And they that erred in spirit shall know understanding, and the murmurers shall learn obedience, and the stammering tongues shall learn to speak peace.

Esias 29:24 In-Context

22 Therefore thus saith the Lord concerning the house of Jacob, whom he set apart from Abraam, Jacob shall not now be ashamed, neither shall he now change countenance.

23 But when their children shall have seen my works, they shall sanctify my name for my sake, and they sanctify the Holy One of Jacob, and shall fear the God of Israel.

24 And they that erred in spirit shall know understanding, and the murmurers shall learn obedience, and the stammering tongues shall learn to speak peace.
