1. Before he sent an angel to raise them up a saviour he sent a prophet to reprove them for sin, and to bring them to repentance, v. 8. This prophet is not named, but he was a man, a prophet, not an angel, as ch. ii. 1. Whether this prophet took an opportunity of delivering his message to the children of Israel when they had met together in a general assembly, at some solemn feast or other great occasion, or whether he went from city to city and from tribe to tribe, preaching to this purport, is not certain; but his errand was to convince them of sin, that, in their crying to the Lord, they might confess that with sorrow and shame, and not spend their breath in only complaining of their trouble. They cried to God for a deliverer, and God sent them a prophet to instruct them, and to make them ready for deliverance. Note, (1.) We have reason to hope God is designing mercy for us if we find he is by his grace preparing us for it. If to those that are sick he sends a messenger, an interpreter, by whom he shows unto man his uprightness, then he is gracious, and grants a recovery, Job xxxiii. 23, 24. (2.) The sending of prophets to a people, and the furnishing of a land with faithful ministers, is a token for good, and an evidence that God has mercy in store for them. He thus turns us to him, and then causes his face to shine, Ps. lxxx. 19.
