Matthew Henry's Commentary
And in that day thou shalt say, O LORD, I will praise thee: though thou wast angry with me, thine anger is turned away, and thou comfortedst me.
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.
Behold, God is my salvation; I will trust, and not be afraid: for the LORD JEHOVAH is my strength and my song; he also is become my salvation.
Therefore with joy shall ye draw water out of the wells of salvation.
And in that day shall ye say, Praise the LORD, call upon his name, declare his doings among the people, make mention that his name is exalted.
Sing unto the LORD; for he hath done excellent things: this is known in all the earth.
Cry out and shout, thou inhabitant of Zion: for great is the Holy One of Israel in the midst of thee.
