Psalm 119: 105-112 Nun: Light, Comfort, Protection-Our Heritage.
The word is not only the first axiom of all thought and existence, it is given with a purpose to the children of the covenant making and covenant keeping LORD-it is our trustworthy guide. One can imagine trying to walk in the midst of darkness and finding the word to be like a lamp to shine light on one’s path (v. 105). “For the commandment is a lamp, and the law a light; reproofs of instruction are the way of life.” (Pr. 6:23 Cf. Ps. 19:8; II Pet. 1:19) Every covenant relationship involves an oath, and so the psalmist swears an oath, which he also confirmed or made good, to keep the righteous judgments of the LORD (v. 106 Cf. Neh. 10:29). It is also given as a word of comfort to the afflicted, through which the LORD revives His people (v. 107).
The psalmist regards his words as a freewill offering which he prays that the LORD would accept, and in turn that the LORD would teach him His judgments (v. 108 Cf. Hos. 14:2; Heb. 13:15). The psalmist’s life was constantly at risk, yet he knew if he kept the law of the LORD it would be his protection against the snares of the wicked (vv. 109-110). The proud seek to set traps for the righteous, because they know they cannot condemn them honestly (Cf. Ps. 140:5). Being a guide, word of comfort, and protection against the wicked, causes the saints to rejoice from the heart in the word, and to cherish it as one’s heritage (v. 111 Cf. Dt. 33:4). The heart is a person’s core, and from the heart the psalmist was inclined to perform the LORD’s statutes, “forever, to the very end.” (v. 112)
