Verse 5
What will ye do in the solemn day - When ye shall be despoiled of every thing by the Assyrians; for the Israelites who remained in the land after its subjection to the Assyrians did worship the true God, and offer unto him the sacrifices appointed by the law, though in an imperfect and schismatic manner; and it was a great mortification to them to be deprived of their religious festivals in a land of strangers. See Calmet.
