And he hath put a new song in my mouth, even praise unto our God: many shall see it, and fear, and shall trust in the LORD.
And he hath put a new song in my mouth - literally, 'He hath given a new song,' etc. The theme of 'the new song,' though one in essential substance, has many particular variations. Redemption is its theme. The song is led by Christ, the Prince-Leader of our salvation, and is taken up by all the redeemed in common (Revelation 1:5-6; Revelation 5:9-10). His deliverance from the grave, and our consequent deliverance through Him, form its subject.
Praise unto our God - "our," not merely 'my God:' for "many" shall form the choir which Messiah leads.
Many shall see it, and fear, and shall trust in the Lord. See and fear, in the Hebrew, form a play on similar sounds х yir'uw (H7200) ... wªyiyraa'uw (H3372)]. The 'sight' of God's deliverance of Christ, first from sin and death, and then of Christ's people through Him, their Saviour, shall create reverent "fear" in many (Psalms 52:4; Psalms 130:4; Jeremiah 33:9). That fear shall not be slavish dread, but fear of offending One who showed His abhorrence of sin, and redeemed us from it at such an awful cost, even the sacrifice of His only-begotten Son; therefore "trust" in Him is inseparably joined to it. The deep internal connection of seeing and fearing God in Christ is marked by the paronomasia.
