I rejoice at thy word, as one that findeth great spoil.

Jamieson-Fausset-Brown Bible Commentary

162. (Compare Mt 13:44, 45). Though persecuted by the mighty, the pious are not turned from revering God's authority to seek their favor, but rejoice in the possession of this "pearl of great price," as great victors in spoils. Hating falsehood and loving truth, often, every day, praising God for it, they find peace and freedom from temptation.

Matthew Henry's Concise Commentary

119:161-168 Those whose hearts stand in awe of God's word, will rather endure the wrath of man, than break the law of God. By the word of God we are unspeakable gainers. Every man hates to have a lie told him, but we should more hate telling a lie; by the latter we give an affront to God. The more we see the beauty of truth, the more we shall see the hateful deformity of a lie. We are to praise God even for afflictions; through grace we get good from them. Those that love the world have great vexation, for it does not answer what they expect; those that love God's word have great peace, for it outdoes what they expect. Those in whom this holy love reigns, will not perplex themselves with needless scruples, or take offence at their brethren. A good hope of salvation will engage the heart in doing the commandments. And our love to the word of God must subdue our lusts, and root out carnal affections: we must make heart work of it, or we make nothing of it. We must keep the commandments of God by obedience to them, and his promises by reliance on them. God's eye is on us at all times; this should make us very careful to keep his commandments.

Matthew Henry's Whole Bible Commentary

Verse 162

Here is, 1. The pleasure David took in the word of God. He rejoiced at it, rejoiced that God had made such a discovery of his mind, that Israel was blessed with that light when other nations sat in darkness, that he was himself let into the understanding of it and had had experience of the power of it. He took a pleasure in reading it, hearing it, and meditating on it, and every thing he met with in it was agreeable to him. He had just now said that his heart stood in awe of his word, and yet here he declares that he rejoiced in it. The more reverence we have for the word of God the more joy we shall find in it. 2. The degree of that pleasure-as one that finds great spoil. This supposes a victory over the enemy. It is through much opposition that a soul comes to this, to rejoice in God's word. But, besides the pleasure and honour of a conquest, there is great advantage gained by the plunder of the field, which adds much to the joy. By the word of God we become more than conquerors, that is, unspeakable gainers.
