Isaiah 30:20 - Matthew Poole's English Annotations on the Holy Bible

And though the Lord give you the bread of adversity, and the water of affliction; and although in that time and state of the church you will be subject to many outward straits and afflictions. This phrase is borrowed from Deuteronomy 16:3 1 Kings 22:27. He seems to allude to the condition of besieged cities, and particularly of Jerusalem, as it was straitened and distressed by Sennacherib, and as it should be far more straitened by the Chaldeans; of which see 2 Kings 25:3. Heb. And the Lord will give, &c. Or, the Lord indeed will give, &c. Yet shall not thy teachers be removed into a corner any more; as they have been in former times, both in Israel and Judah, when the godly prophets and ministers were but few, and when they were persecuted and banished by their wicked rulers. But in the New Testament God hath made better provision for his church, sending his Son, the great Teacher of the church, into the world, and pouring forth the gifts and graces of the Spirit in abundance, and increasing the number of able and faithful ministers, and promising a continued succession of them to the end of the world, Matthew 28:19,20. Thine eyes shall see thy teachers; thou shalt have their presence, and their instruction and assistance.
