Isaiah 12:2

2 Surely God is my salvation; I will trust and not be afraid. For the LORD GOD is my strength and my song, and He also has become my salvation.”

Isaiah 12:2 Meaning and Commentary

Isaiah 12:2

Behold, God [is] my salvation
Or Saviour; that is, Christ, who is God, the great God, and so fit to be a Saviour, and is one, was appointed by the Father, provided in covenant, promised in the word, sent in the fulness of time, and is become the author of salvation, which a creature could not be; and this the church saw her interest in, and which was the ground of her comfort before declared; and to which she prefixed the word "behold", as a note of asseveration, affirming him to be her Saviour; and of admiration, wondering at it; and of exclusion of all others from being concerned therein; and of attention and direction to others, pointing him out as the only one to look unto. I will trust, and not be afraid;
"trust" in Christ for salvation, be confident of enjoying it, and look upon myself safe and secure from all wrath and condemnation, and from every enemy; and not be "afraid" of sin, Satan, the world, death, hell, and wrath to come. The Targum joins this and the preceding clause together,

``behold, in the word of God my salvation I trust, and shall not be moved:''

for the LORD JEHOVAH [is] my strength and [my] song;
the author of her spiritual strength; the "strength" of her life, and of her heart, which maintained the one, and supported the other; the strength of her graces, and of her duties, by which she exercised the one, and performed the other: and the subject matter of her "song" were his person, and the fulness and fitness of it, his righteousness, and salvation by him; this clause, and the following one, are taken out of ( Exodus 15:2 ) : he also is become my salvation;
salvation is wrought out by Christ, and believers have it in him, and they know it, and believe it, and so are already saved in him.

Isaiah 12:2 In-Context

1 In that day you will say: “O LORD, I will praise You. Although You were angry with me, Your anger has turned away, and You have comforted me.

2 Surely God is my salvation; I will trust and not be afraid. For the LORD GOD is my strength and my song, and He also has become my salvation.”

3 With joy you will draw water from the springs of salvation,

4 and on that day you will say: “Give praise to the LORD; proclaim His name! Make His works known among the peoples; declare that His name is exalted.

5 Sing to the LORD, for He has done glorious things. Let this be known in all the earth.
