(20-22) Hope--wait--trust.--The Hebrew language was naturally rich in words expressive of that attitude of expectancy which was characteristic of a nation whose golden age was not in the past, but in the future--a nation for which its great ancestor left in his dying words so suitable a motto--

"I have waited for thy salvation, O Lord,"

and which, while itself held back outside the promised land of the hope of immortality, was to be the birth-race of the great and consoling doctrine that alone could satisfy the natural craving expressed by the moralist in the well-known line--

"Man never is, but always to be, blest;"

and by the Christian apostle--

"For here we have no continuing city, but we seek one to come."

Verses 20-22. - A brief address of the people to God, arising out of what has been declared concerning his goodness (vers. 4, 5, 12-19) and his power (vers. 6-11), which constitute a call upon them for praise and adoration. Verse 20. - Our soul waiteth for the Lord (comp. Psalm 25:21; Psalm 62:1, 5; Psalm 130:5, 6, etc.). Confident in God's good will, and in his power to help us, we wait patiently and cheerfully for him to manifest himself in his own good time. He is our Help and our Shield. We trust in no one and nothing but him - not in armies (ver. 16), not in horses (ver. 17), not in our own strength (ver. 16). He alone is our dependence. (For the use of the metaphor "shield" for defence, see Psalm 5:12; Psalm 18:2; Psalm 28:7; Psalm 91:4; Psalm 119:114, etc.)

33:12-22 All the motions and operations of the souls of men, which no mortals know but themselves, God knows better than they do. Their hearts, as well as their times, are all in his hand; he formed the spirit of each man within him. All the powers of the creature depend upon him, and are of no account, of no avail at all, without him. If we make God's favour sure towards us, then we need not fear whatever is against us. We are to give to him the glory of his special grace. All human devices for the salvation of our souls are vain; but the Lord's watchful eye is over those whose conscientious fear of his name proceeds from a believing hope in his mercy. In difficulties they shall be helped; in dangers they shall not receive any real damage. Those that fear God and his wrath, must hope in God and his mercy; for there is no flying from him, but by flying to him. Let thy mercy, O Lord, be upon us; let us always have the comfort and benefit, not according to our merits, but according to the promise which thou hast in thy word given to us, and according to the faith thou hast by thy Spirit and grace wrought in us.Our soul waiteth for the Lord,.... This, and what follows, are the words of the church, expressing her expectation, faith, and joy, by reason of what is suggested in the preceding verses. She signifies her expectation of good by waiting for the Lord; either for his coming in the flesh, and salvation by him; for which the patriarchs, prophets, and all the Old Testament saints, waited, Genesis 49:18; and so the Targum paraphrases it, "our soul waiteth for the redemption of the Lord"; or for his spiritual coming, his appearance to them, and gracious presence with them, he having been for some time absent; and it is right and good so to do, and in the issue proves advantageous, Isaiah 8:17; and this being soul waiting, it denotes the heartiness, sincerity, and earnestness of it;

he is our help and our shield; the Lord is the help of his people in time of trouble, when none else is or can be; and he is a present one, and helps right early, and at the best season: and he is their shield, who encompasses them about with his love and favour, and keeps them by his power in the greatest safety; all which encourages their waiting upon him, and expectation of good things from him.
