Isaiah 37:21
Then Isaiah the son of Amoz sent unto Hezekiah, saying, Thus saith the LORD God of Israel, Whereas thou hast prayed to me against Sennacherib king of Assyria:
Then Isaiah the son of Amoz sent unto Hezekiah, saying,.... Isaiah, by a spirit of prophecy, was made acquainted by the Lord both with the prayer of Hezekiah, and the Lord's answer to it; and therefore immediately sent to the king, who was either at the temple praying, or was returned to the palace, to let him know, the mind of the Lord in this matter. The Septuagint and Syriac versions render it, "and Isaiah the son of Amoz was sent to Hezekiah"; but this does not agree with the Hebrew text; Isaiah sent messengers to the king, and by them informed him what the Lord had said in answer to his prayer. Why he went not himself cannot be said:
Thus saith the LORD God of Israel; Hezekiah had been praying to him under that title and character, Isaiah 37:16:
Whereas thou hast prayed to me against Sennacherib king of Assyria: or, "what thou hast prayed", &c. {n}; the Septuagint, Syriac, and Arabic versions, supply, "I have heard". It is bad for any to have the prayers of good men against them.
