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.
Verses 1-6. - THE SONG OF THANKSGIVING OF THE UNITED CHURCH. On each of her deliverances the Church is hound to praise God. In some parts of the Church it is customary on every such occasion to sing a "Te Deum." The ordinary Israelite hymn of praise appears to have been the hundred and thirty-sixth psalm (1 Chronicles 16:34, 41; 2 Chronicles 5:13; 2 Chronicles 7:3; Ezra 3:11; Jeremiah 33:11; 1 Macc. 4:24); but on extraordinary occasions special thanksgivings were sung (Exodus 15:1-21; 1 Samuel 7:18-29, etc.). Isaiah is now inspired to give a pattern song, suitable for the Church to sing when she is reunited, enlarged, and restored to favor. Verse 1. - In that day. In the day of deliverance and restoration. Though thou wast angry; literally, because thou wast angry. Kay understands an actual hank-fullness for the severe discipline, which had checked them, and not allowed them to glide on smoothly to ruin. But perhaps the idiom is rather that of the passage, "Father, I thank thee that thou hast hid these things from the wise and prudent, and hast revealed them unto babes" (Matthew 11:25), where it is only the last clause that expresses the true object of the thanksgiving. Comfortedst; rather, hast comforted, since the effect continued.
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.
Verse 2. - God is my salvation (comp. Psalm 27:1; Psalm 38:22, etc.). The employment of the abstract "salvation" for the concrete "Savior" is extremely common. The Lord Jehovah; literally, Jab Jehovah - a combination which occurs only here and in Isaiah 26:4, where it is again used as an encouragement to perfect confidence and trust. Is my strength... salvation. This is quoted from the song of Moses (Exodus 15:2), which the prophet has throughout in his thoughts.
Therefore with joy shall ye draw water out of the wells of salvation.
Verse 3. - With joy shall ye draw water. The prophet interrupts the song to give a comforting promise. The "salvation" granted to the Church shall be as an inexhaustible well, from which all comers may draw continually. Compare our Lord's promise to the woman of Samaria in John 4:14.
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.
Verse 4. - Declare his doings among the people; literally, among the peoples (comp. Psalm 9:11; Psalm 77:12; Psalm 107:22; Psalm 118:17). It is always regarded as one of man's chief duties to testify of God's goodness to others. Here Israel is called upon to publish God's mercies and great deeds to the Gentiles. His name is exalted. God is in his Name, and his Name expresses his nature. As there is nothing so exalted in all the universe as God, so there is no name so exalted as his Name. Hence his Name is protected by an express commandment.
Sing unto the LORD; for he hath done excellent things: this is known in all the earth.
Verse 5. - Sing unto the Lord; for he hath done excellent things. This is another quotation, very slightly modified, from the song of Moses, in which these words were part of the refrain (Exodus 15:1, 21). This is known; rather, let this be known; i.e. publish it - noise it abroad.
Cry out and shout, thou inhabitant of Zion: for great is the Holy One of Israel in the midst of thee.
Verse 6. - Cry out and shout, thou inhabitant of Zion; i.e. raise a "cry" that may be heard far and wide - a cry that shall be a "shout" of rejoicing. The wool translated "inhabitant" is feminine, and designates the entire community or Church that dwells on the holy hill. For great is the Holy One of Israel in the midst of thee. The crowning glory of the Church is the presence of her Lord in the midst of her a presence continuous ("I am with you always"), efficacious (John 15:4-6), yet invisible (1 Peter 1:8). The Church is ever to proclaim this presence and rejoice in it.
