Isaiah 48:18 Meaning and Commentary

Isaiah 48:18

O that thou hadst hearkened to my commandments
Which the Jews did not, but slighted and despised them, and were not obedient to them. So, in the times of Christ, they disregarded his doctrines, though so profitable; and despised his ordinances and commands, which were not grievous; they neither hearkened to them themselves, nor would suffer others; wherefore our Lord expresses his great concern at it, and his desire, as man, after their welfare; see ( Matthew 23:13 Matthew 23:37 ) : then had thy peace been as a river:
their prosperity, temporal and spiritual, had been abundant, and would have always continued, have been increasing and ever flowing, yea, overflowing, like the waters of a river. The Targum is, the river Euphrates, a river which ran through Babylon: but they had no regard to the things which related to their temporal, spiritual, and eternal peace, these were hid from their eyes, ( Luke 19:42 ) : and thy righteousness as the waves of the sea:
large, abundant, numerous as the waves of the sea; which may regard acts of justice and righteousness, which are the support of a people and state, and blessings the fruit thereof; and which God of his goodness bestows on such a people, as all kind of prosperity, protection, safety, and continuance.

Isaiah 48:18 In-Context

16 Come near to me, and give ear to this; from the start I did not keep it secret; from the time of its coming into existence I was there: and now the Lord God has sent me, and given me his spirit.

17 The Lord who takes up your cause, the Holy One of Israel, says, I am the Lord your God, who is teaching you for your profit, guiding you by the way in which you are to go.

18 If only you had given ear to my orders, then your peace would have been like a river, and your righteousness as the waves of the sea:

19 Your seed would have been like the sand, and your offspring like the dust: your name would not be cut off or come to an end before me.

20 Go out of Babylon, go in flight from the Chaldaeans; with the sound of song make it clear, give the news, let the word go out even to the end of the earth: say, The Lord has taken up the cause of his servant Jacob.
