My soul shall make her boast in Jehovah. The term soul in this place signifies not the vital spirit, but the seat of the affections; as if David had said, I shall always have ground of boasting with my whole heart in God alone, so that I shall never suffer myself to fall into forgetfulness of so great a deliverance. In the second clause he specifies this as the fruit of his thanksgiving, that the afflicted and miserable shall derive from it ground of hope. The Hebrew word nvym, anavim, which we have rendered humble, signifies not all the afflicted [1] in general, but those who, being humbled and subdued by afflictions, instead of breathing the spirit of pride, are cast down, and ready to abase themselves to the very dust. These, he says, shall be partakers of his joy; but not, as some have coldly explained it, simply from a feeling of sympathy, but because, being persuaded that in the example of David, God had given them a general testimony of his grace, their hearts would recover from sorrow, and would be lifted up on high. Accordingly, he says that this joy shall spring from hope, because, having received a pledge of their deliverance, they shall cheerfully have recourse to God.

Footnotes

1 - The word nvym, anavim, may also be rendered the afflicted. Our author in his exposition combines both the ideas of humble and afflicted.

My soul shall make her boast in the Lord - I myself will rejoice and exult in him. The word "boast" here refers to that on which a man would value himself; that which would be most prominent in his mind when he endeavored to call to remembrance what he could reflect on with most pleasure. The psalmist here says that when He did this, it would not be wealth or strength to which he would refer; it would not be his rank or position in society; it would not be what he had done, nor what he had gained, as pertaining to this life. His joy would spring from the fact that there was a God; that he was such a God, and that he could regard him as His God. This would be his chief distinction - that on which he would value himself most. Of all the things that we can possess in this world, the crowning distinction is, that we have a God, and that he is such a being as he is.
The humble shall hear thereof - The poor; the afflicted; those who are in the lower walks of life. They should hear that he put his trust in God, and they should find joy in being thus directed to God as their portion and their hope. The psalmist seems to have referred here to that class particularly, because:
(a) they would be more likely to appreciate this than those of more elevated rank, or than those who had never known affliction; and
(b) because this would be specially fitted to impart to them support and consolation, as derived from his own experience.
He had been in trouble. He had been encompassed with dangers. He had been mercifully protected and delivered. He was about to state how it had been done. He was sure that they who were in the circumstances in which he had been would welcome the truths which he was about to state, and would rejoice that there might be deliverance for them also, and that they too might find God a protector and a friend. Calamity, danger, poverty, trial, are often of eminent advantage in preparing the mind to appreciate the nature, and to prize the lessons of religion.
And be glad - Rejoice in the story of my deliverance, since it will lead them to see that they also may find deliverance in the day of trial.

My soul shall make her boast - Shall set itself to praise the Lord - shall consider this its chief work.
The humble - ענוים anavim, the afflicted, such as David had been.

My soul shall make her boast in the LORD: the (b) humble shall hear [thereof], and be glad.
(b) They who are beaten down with the experience of their own evils.

My soul shall make her boast in the Lord,.... Not in men, nor in any outward enjoyment, nor in any works of righteousness, but in the Lord; "in the Word of the Lord", as the Targum; in the Lord Jesus Christ; in his wisdom, strength, riches, righteousness, redemption, and salvation; in interest in him, and communion with him: and this is not tongue but soul boasting; and not flashy and selfish, but solid, spiritual, and hearty; and with all the powers and faculties of the soul; see 1-Corinthians 1:29;
the humble shall hear thereof; either of the deliverance the psalmist had out of the hands of his enemies; or of his blessing and praising the Lord for the same, and making his boast in him as the God of his salvation; or of both: of these humble ones; see Gill on Psalm 10:12;
and be glad; for such rejoice with them that rejoice, and are glad at heart that others share in the goodness and grace of God; and also because by such an instance of the divine power and kindness they are encouraged to hope that he will, in his own time, deliver them out of their afflictions and distresses also.

make her boast--"glory" (Psalm 105:3; compare Galatians 6:14).
humble--"the pious," as in Psalm 9:12; Psalm 25:9.

Shall boast - Shall glory in this, that I have so powerful and so gracious a master. The humble - The righteous.
