After three chapters of prophecy against Israel, the Lord now turns his attention to what is going to happen to Israel after the Second Coming of Jesus.  Chapter 4 only has six verses, so the Lord just covers a few areas of the restoration of Israel.

Israel’s population will increase – v.1 – in the Tribulation, Israel will be nearly decimated, Is 1:7-9; 3:25; 10:20-23 – the females will outnumber the males by 7:1 and they will be willing to provide for themselves just for the chance to marry – the expression “called by thy name” shows that she takes the name of her husband after marriage [Gen 5:2].

Israel will prosper – v.2 – the branch of the Lord is a reference to Israel – it was originally planted in Canaan after Israel left Egypt and wandered in the wilderness [Ps 80:8-18] – at first it flourished – but after time the branch was nearly destroyed – it will suffer terribly during the Tribulation but during the millennial reign of Jesus it will be beautiful and glorious – compare Rev 8:7 with Amos 9:11-15.

Israel will be holy – v.3 – Is 52:1, Oba 17 – that’s because they will be fully under the new covenant of Jer 31:31-34 – for the expression “written among the living” see Ps 87.

Their filth and blood will have been washed and purged – v.4 – this is the result of the new covenant that will be in full effect during the millennium – filth washed, see Is 3:24 – blood of Jerusalem, see Ezek 22:1-6, Joel 3:21 – spirit of judgment, see Deut 32:35-39 – spirit of burning, see Mal 3:2, 2 Thes 1:7-9, 2 Thes 2:8.

They will be protected by the Lord’s presence – v.5 – when the Lord’s presence was upon the tabernacle, this cloud and fire were evident [Ex 40:34-38; 13:21; 14:14, 19-20] – in Jerusalem, the Lord’s presence will be manifested by this cloud, smoke and flaming fire – they will be evident on “every dwelling place of Mount Zion” – see Zech 2:5.

They will have a tabernacle for protection – v.6 – this tabernacle will provide shade from the heat and a covering from the storm and rain [Rev 7:16-17; Is 25:4; Joel 2:23].
