Charles Ellicott Commentary 2 Kings 20:19

"Then said Hezekiah unto Isaiah, Good is the word of Jehovah which thou hast spoken. He said moreover, Is it not so, if peace and truth shall be in my days?" — 2 Kings 20:19 (ASV)

Good is the word of the Lord ... —Pious acquiescence in the will of God. (Compare Eli’s: It is the Lord: let him do what seemeth him good. Compare also a similar expression in 1 Kings 2:38.)

Is it not good, if peace ... —This rendering appears to be right. Severe as is the prophetic word of judgment, it contains an element of mercy, in that Hezekiah himself is spared. The words are introduced by and he said, to indicate that they were spoken after a pause.

Peace and truth. —Rather, peace and permanence (or, security, stability; Jeremiah 33:6). Ewald, Thenius, and Bähr render: “Yea, only may there be peace, etc., in my days.” (Compare the prayer of the church: “Give peace in our time, O Lord.”)
