Jeremiah 30:7

that day The expression "the day of the Lord," in an eschatological sense, is found first in Amos (Jeremiah 5:18), and is adopted by later prophets. Its meaning is developed in two directions according to the teaching which the individual prophet desires to convey. Jehovah, they taught, will some day manifest Himself, it may be in executing terrible judgement upon the sin either of His own nation or of others; but it may also be in the restoration of the former to the privileges which they had forfeited. The description is modified in each case by the occasion; e.g. Isaiah 2:12 ff. directs the judgement against the material wealth and luxury acquired in the days of Uzziah. Joel (Jeremiah 2:1 ff.) illustrates the punishment by a recent scourge of locusts. Cp. Zephaniah 1:7; Zephaniah 1:14 ff. Here, and in later prophecy in general (see above for the date of this section), the Day results in Israel's deliverance, a deliverance reached, however, only through suffering.

he shall be saved out of it Here we have the transition to the joyous note which dominates the rest of the prophecy.
