The voice of rejoicing and salvation is in the tabernacles of the righteous: the right hand of the LORD doeth valiantly.
The voice of rejoicing and salvation is in the tabernacles of the righteous - (Isaiah 12:3.) Joy was the distinguishing characteristic of the feast of tabernacles. The booths and lulabs had a gay effect by day; the flambeaux, the music, and the joyous gatherings in the temple, had a still more joyous effect by night. The proverb in Succah (Psalms 118:1) is, 'He who has never seen the rejoicing at the pouring out of the water of Siloam has never seen rejoicing in His life.' It was a thanksgiving for the rest (cf. Psalms 116:7) of the Israelites in the promised land after their restless sojourn in tabernacles in the wilderness. As God rested on the seventh day, so Israel's rest was celebrated on the fifteenth of the seventh month. It was also a thanksgiving for the ingathered harvest, as the Passover in the first month, Abib, was marked by offering the first sheaf of barley, and Pentecost, fifty days after, by waving the first loaves of the year before the altar. The feast was appropriately connected with the dedication of the first temple, and the erection of the altar of the second temple, the culminating point of the nation's rest and settlement, religious and civil, in the promised land (1 Kings 8:2; 1 Kings 8:65; Ezra 3:2-4), and finally at the completion of the city wall, and setting up of the temple doors (Nehemiah 7:1; Nehemiah 8:14-18). Zechariah 14:15 shows us that in the millennial Jerusalem there shall be, 'from year to year,' a going up of all the nations to Jerusalem (by delegates) 'to keep the feast of tabernacles,' and 'to worship the King, the Lord of hosts.' This certainly has not yet been fulfilled. Compare Hosea 12:9. "The righteous" are Israel, literal and spiritual (Isaiah 26:2). "The voice of salvation" is the voice that celebrates the salvation already performed for Israel.
The right hand of the Lord doeth valiantly. If 'we do valiantly' (Psalms 108:13), it is 'through God,' who "doeth valiantly" for us (Psalms 60:12).
