Thou wilt keep him - The following verses to Isaiah 26:11, contain moral and religious reflections, and seem designed to indicate the resignation evinced by the 'righteous nation' during their long afflictions. Their own feelings they are here represented as uttering in the form of general truths to be sources of consolation to others.

In perfect peace - Hebrew as in the Margin, 'Peace, peace;' the repetition of the word denoting, as is usual in Hebrew, emphasis, and here evidently meaning undisturbed, perfect peace. That is, the mind that has confidence in God shall not be agitated by the trials to which it shall be subject; by persecution, poverty, sickness, want, or bereavement. The inhabitants of Judea had been borne to a far distant land. They had been subjected to reproaches and to scorn Psalm 137:1-9; had been stripped of their property and honor; and had been reduced to the condition of prisoners and captives. Yet their confidence in God had not been shaken. They still trusted in him; still believed that he could and would deliver them. Their mind was, therefore, kept in entire peace. So it was with the Redeemer when he was persecuted and maligned (1 Peter 2:23; compare Luke 23:46). And so it has been with tens of thousands of the confessors and martyrs, and of the persecuted and afflicted people of God, who have been enabled to commit their cause to him, and amidst the storms of persecution, and even in the prison and at the stake, have been kept in perfect peace.

Whose mind is stayed on thee - Various interpretations have been given of this passage, but our translation has probably hit upon the exact sense. The word which is rendered 'mind' (יצר yētser) is derived from יצר yâtsar to form, create, devise; and it properly denotes that which is formed or made Psalm 103:14; Isaiah 29:16, Hebrews 2:18. Then it denotes anything that is formed by the mind - its thoughts, imaginations, devices Genesis 8:21; Deuteronomy 31:21. Here it may mean the thoughts themselves, or the mind that forms the thoughts. Either interpretation suits the connection, and will make sense. The expression, 'is stayed on thee,' in the Hebrew does not express the idea that the mind is stayed on God, though that is evidently implied. The Hebrew is simply, whose mind is stayed, supported (סמוּך sâmûk); that is, evidently, supported by God. There is no other support but that; and the connection requires us to understand this of him.

In perfect peace - שלום שלום shalom, shalom, "peace, peace, "i.e., peace upon peace - all kinds of prosperity - happiness in this world and in the world to come.

Because he trusteth in thee "Because they have trusted in thee" - So the Chaldee, בטחו betacho. The Syriac and Vulgate read בטוח batachnu, "we have trusted. "Schroeder, Gram. Hebrews p. 360, explains the present reading בטוח batuach, impersonally, confisum est.

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 Psalm 72:7,

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,

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.

The relation of Israel and Jehovah to one another is now a permanent one. "Thou keepest the firmly-established mind in peace, peace; for his confidence rests on Thee." A gnome (borrowed in Psalm 112:7-8), but in a lyrical connection, and with a distinct reference to the church of the last days. There is no necessity to take סמוּ יצר as standing for יצר סמוּך, as Knobel does. The state of mind is mentioned here as designating the person possessing it, according to his inmost nature. יצר (the mind) is the whole attitude and habit of a man as inwardly constituted, i.e., as a being capable of thought and will. סמוּך is the same, regarded as having a firm hold in itself, and this it has whenever it has a firm hold on God (Isaiah 10:20). This is the mind of the new Israel, and Jehovah keeps it, shâlom, shâlom (peace, peace; accusative predicates, used in the place of a consequential clause), i.e., so that deep and constant peace abides therein (Philippians 4:7). Such a mind is thus kept by Jehovah, because its trust is placed in Jehovah. בּטוּח refers to יצר, according to Ewald, 149, d, and is therefore equivalent to הוּא בּטוּח (cf., Psalm 7:10; Psalm 55:20), the passive participle, like the Latin confisus, fretus. To hang on God, or to be thoroughly devoted to Him, secures both stability and peace.

Thou wilt keep him in perfect peace, whose {d} mind is stayed on thee: because he trusteth in thee.

(d) You have decreed so, and your purpose cannot be changed.

3. mind . stayed-(Ps 112:7, 8). Jesus can create "perfect peace" within thy mind, though storms of trial rage without (Isa 57:19; Mr 4:39); as a city kept securely by a strong garrison within, though besieged without (so Php 4:7). "Keep," literally, "guard as with a garrison." Horsley translates, (God's) workmanship (the Hebrew does not probably mean "mind," but "a thing formed," Eph 2:10), so constantly "supported"; or else "formed and supported (by Thee) Thou shalt preserve (it, namely, the righteous nation) in perpetual peace."

26:1-4 That day, seems to mean when the New Testament Babylon shall be levelled with the ground. The unchangeable promise and covenant of the Lord are the walls of the church of God. The gates of this city shall be open. Let sinners then be encouraged to join to the Lord. Thou wilt keep him in peace; in perfect peace, inward peace, outward peace, peace with God, peace of conscience, peace at all times, in all events. Trust in the Lord for that peace, that portion, which will be for ever. Whatever we trust to the world for, it will last only for a moment; but those who trust in God shall not only find in him, but shall receive from him, strength that will carry them to that blessedness which is for ever. Let us then acknowledge him in all our ways, and rely on him in all trials.
