Isaiah 26:3

3 The eld error is gone away; thou shalt keep peace, peace, for thou, Lord, we hoped in thee. (Thou shalt keep us in peace, Lord, for we have put away the old errors, yea, in perfect peace, for we who hope in thee.)

Isaiah 26:3 Meaning and Commentary

Isaiah 26:3

Thou wilt keep [him] in perfect peace
Peace with God in Christ through his blood, in a way of believing, and as the fruit and effect of his righteousness being received by faith; this is not always felt, received, and enjoyed in the soul; yet the foundation of it always is, and is perfect; and besides, this peace is true, real, and solid; in which sense the word "perfect" is used, in opposition to a false and imaginary one; and it will end in perfect peace in heaven: moreover, the word "perfect" is not in the Hebrew text, it is there "peace, peace"; which is doubled to denote the certainty of it, the enjoyment of it, and the constancy and continuance of it; and as expressive of all sorts of peace, which God grants unto his people, and keeps for them, and them in; as peace with God and peace with men, peace outward and peace inward, peace here and peace hereafter; and particularly it denotes the abundance of peace that believers will have in the kingdom of Christ in the latter day; see ( Psalms 72:7 ) ( Isaiah 9:7 ) : [whose] mind [is] stayed [on thee];
or "fixed" on the love of God, rooted and grounded in that, and firmly persuaded of interest in it, and that nothing can separate from it; on the covenant and promises of God, which are firm and sure; and on the faithfulness and power of God to make them good, and perform them; and on Christ the Son of God, and Saviour of men; upon him as a Saviour, laying the whole stress of their salvation on him; upon his righteousness, for their justification; upon his blood and sacrifice, for atonement, pardon, and cleansing; on his fulness, for the supply of their wants; on his person, for their acceptance with God; and on his power, for their protection and preservation; see ( Isaiah 10:20 ) ( 50:10 ) ( Psalms 112:7 Psalms 112:8 ) : because he trusteth in thee;
not in the creature, nor in any creature enjoyment, nor in their riches, nor in their righteousness, nor in their own hearts, nor in any carnal privileges: only in the Lord, as exhorted to in the next verse ( Isaiah 26:4 ) ; in the Word of the Lord, as the Targum, that is, in Christ.

Isaiah 26:3 In-Context

1 In that day this song shall be sung in the land of Judah. The city of our strength; the saviour shall be set therein, the wall and the forewall, either a stronghold before the wall. (On that day this song shall be sung in the land of Judah. The city of our strength; salvation shall be found there, yea, the wall and the forewall, that is, a stronghold in front of the wall.)

2 Open ye the gates, and the just folk shall enter, keeping truth. (Open ye the gates, and the just nation shall enter in/and the righteous people shall enter in, keeping faith.)

3 The eld error is gone away; thou shalt keep peace, peace, for thou, Lord, we hoped in thee. (Thou shalt keep us in peace, Lord, for we have put away the old errors, yea, in perfect peace, for we who hope in thee.)

4 Ye have hoped in the Lord, in everlasting worlds, in the Lord God, strong without end. (Yea, hope ye in the Lord, forever, in the Lord God, who shall be strong forever.)

5 For he shall bow down them that dwell on high, and he shall make low an high city; he shall make it low till to the earth; he shall draw it down till to the dust. (For he shall bow down those who be proud, or be haughty, and he shall make low a high city; he shall make it low unto the ground; he shall draw it down unto the dust.)
