In that day it shall be said to Jerusalem, Fear thou not - For "perfect love casteth out fear" John 4:18; from where he saith, "Fear not, little flock; it is your Father's good pleasure to give you the kingdom" Luke 12:32. Who then and what should the Church or the faithful soul fear, since "mightier is He that is in her, than he that is in the world? And to Zion, Let not thine hands be slack," through faint-heartedness (see Hebrews 12:12), but work with all thy might; be ready to do or bear anything; since Christ worketh with, in, by thee, and "in due time we shall reap, if we faint not" Galatians 6:9.

Fear thou not - Thou shalt have no more captivities nor national afflictions.

Let not thine hands be slack - This may refer, first, to the rebuilding of the temple of God, after the return from Babylon; and, secondly, to their diligence and zeal in the Christian Church.

In that day it shall be said to Jerusalem, fear thou not,.... Do not be afraid of any enemies; neither outward ones, the armies of Gog and Magog, the Turk, who will threaten, and will attempt to dispossess them of their land, now returned to it; nor inward and spiritual enemies, sin, Satan, death, and hell, being all vanquished and subdued by Christ: this will be said, not by the enemies themselves, who will confess they have no power to stand before the mighty God, as Aben Ezra; but either by the prophets of the Lord, or by the people themselves, encouraging one another, every man his neighbour, as Kimchi; or rather by the Lord himself, as the Septuagint and Arabic versions supply it,

"the Lord shall say to Jerusalem;''

this will be said at the time of the Jews' conversion, when reinstated in their own land, and shall be threatened with another remove from it, which they will have no reason to fear:

and to Zion, Let not thine hands be slack; weak, remiss, hang down through fear of mind, and fainting of spirit; and so unfit to meet the enemy, or perform duty; but, on the contrary, pluck up a good heart, be of good courage, fear not the enemy, be vigorous, active, and diligent, in the performance of the service of the Lord, animated by the following considerations:

In that day it shall be said to Jerusalem, Fear thou not: and to Zion, Let not thine hands be slack.

slack: or, faint

16. Let not thine hands be slack-(Heb 12:12). Do not faint in the work of the Lord.

3:14-20 After the promises of taking away sin, follow promises of taking away trouble. When the cause is removed, the effect will cease. What makes a people holy, will make them happy. The precious promises made to the purified people, were to have full accomplishment in the gospel. These verses appear chiefly to relate to the future conversion and restoration of Israel, and the glorious times which are to follow. They show the abundant peace, comfort, and prosperity of the church, in the happy times yet to come. He will save; he will be Jesus; he will answer the name, for he will save his people from their sins. Before the glorious times foretold, believers would be sorrowful, and objects of reproach. But the Lord will save the weakest believer, and cause true Christians to be greatly honoured where they had been treated with contempt. One act of mercy and grace shall serve, both to gather Israel out of their dispersions and to lead them to their own land. Then will God's Israel be made a name and a praise to eternity. The events alone can fully answer the language of this prophecy. Many are the troubles of the righteous, but they may rejoice in God's love. Surely our hearts should honour the Lord, and rejoice in him, when we hear such words of condescension and grace. If now kept from his ordinances, it is our trial and grief; but in due time we shall be gathered into his temple above. The glory and happiness of the believer will be perfect, unchangeable, and eternal, when he is freed from earthly sorrows, and brought to heavenly bliss.
