Amos 5:16

Here is, I. A very terrible threatening of destruction approaching, Amo 5:16, Amo 5:17. Since they would not take the right course to obtain the favour of God, God would take an effectual course to make them feel the weight of his displeasure. The threatening is introduced with more than ordinary solemnity, to strike an awe upon them; it is not the word of the prophet only (if so, it might be made light of) but it is the Lord Jehovah, who has an infinite eternal being; it is the God of hosts, who has a boundless irresistible power, and it is Adonai - the Lord, who has an absolute incontestable sovereignty, and a universal dominion; it is he who says it, who can and will make his words good, and he has said, 1. That the land of Israel shall be put in mourning, true mourning, that all places shall be filled with lamentation for the calamities coming upon them. Look into the cities, and wailing shall be in all streets, in the great streets, in the by-streets. Look into the country, and they shall say in all the highways, Alas! alas! we are all undone! The lamentation shall be so great as not to be confined within doors, nor kept within the bounds of decency, but it shall be proclaimed in the streets and highways, and shall run wild.

Therefore--resumed from Amo 5:13. God foresees they will not obey the exhortation (Amo 5:14-15), but will persevere in the unrighteousness stigmatized (Amo 5:7, Amo 5:10, Amo 5:12). the Lord--JEHOVAH. the God of hosts, the Lord--an accumulation of titles, of which His lordship over all things is the climax, to mark that from His judgment there is no appeal. streets . . . highways--the broad open spaces and the narrow streets common in the East. call the husbandman to mourning--The citizens shall call the inexperienced husbandmen to act the part usually performed by professional mourners, as there will not be enough of the latter for the universal mourning which prevails. such as are skilful of lamentation--professional mourners hired to lead off the lamentations for the deceased; alluded to in Ecc 12:5; generally women (Jer 9:17-19).
