12:10-16 When the gospel should be publicly preached, the Gentiles would seek Christ Jesus as their Lord and Saviour, and find rest of soul. When God's time is come for the deliverance of his people, mountains of opposition shall become plains before him. God can soon turn gloomy days into glorious ones. And while we expect the Lord to gather his ancient people, and bring them home to his church, also to bring in the fulness of the Gentiles, when all will be united in holy love, let us tread the highway of holiness he has made for his redeemed. Let us wait for the mercy of our Lord Jesus Christ unto eternal life, looking to him to prepare our way through death, that river which separates this world from the eternal world.

2. Lord Jehovah—Jah, Jehovah. The repetition of the name denotes emphasis, and the unchangeableness of God's character.

strength … song … salvation—derived from Ex 15:2; Ps 118:14. The idea of salvation was peculiarly associated with the feast of tabernacles (see Isa 12:3). Hence the cry "Hosanna," "Save, we beseech thee," that accompanied Jesus' triumphal entry into Jerusalem on that day (the fifteenth of the seventh month) (Mt 21:9; compare with Ps 118:25, 26); the earnest of the perfected "salvation" which He shall bring to His people at His glorious second appearance at Jerusalem (Heb 9:28). "He shall appear the second time without sin unto salvation." Compare Re 21:3, "The tabernacle of God is with men." Compare Lu 9:33, "three tabernacles: one for thee," &c. (the transfiguration being a pledge of the future kingdom), (Ps 118:15; Zec 14:16). As the Jew was reminded by the feast of tabernacles of his wanderings in tents in the wilderness, so the Jew-Gentile Church to come shall call to mind, with thanksgiving, the various past ways whereby God has at last brought them to the heavenly "city of habitation" (Ps 107:7).
