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 Mat 23:13 , 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, Luk 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.
