2 Kings 20:19

Then said Hezekiah unto Isaiah, Good [is] the word of the LORD which thou hast (l) spoken. And he said, [Is it] not [good], if (m) peace and truth be in my days?

(l) He acknowledges Isaiah to be the true prophet of God and therefore humbles himself to his word.

(m) Seeing that God has shown me this favour to grant me quietness during my life: for he was afraid lest the enemies would have had opportunity to rejoice if the Church had decayed in his time, because he had restored religion.
