Behold, at that time I will deal with all them that afflict thee; and I will save that which is lame, and gather that which was driven away; and I will make them a praise and a name, whose shame hath been in all the earth.
undo--MAURER translates, "I will deal with," that is, as they deserve. Compare Eze 23:25, where the Hebrew is similarly translated. The destruction of Israel's foes precedes Israel's restoration (Isa 66:15-16). her that halteth--all that are helpless. Their weakness will be no barrier in the way of My restoring them. So in Psa 35:15, Margin, "halting" is used for adversity. Also Eze 34:16; Mic 4:6-7.
He confirms here what I have referred to in the last verse that God would overcome all obstacles, when his purpose was to restore his people. On this the Prophet, as we have said, dwells, that the Jews might in their exile sustain themselves with the hope of deliverance.
Zep 3:18-20 “I gather together those that mourn for the festive meeting; they are of thee; reproach presses upon them. Zep 3:19. Behold, at that time I will treat with all thine oppressors, and will save the limping, and gather together that which is dispersed, and make them a praise and a name in every land of their shame. Zep 3:20.
