Psalms 43:3

“O send out thy light and thy truth, etc.] By light is meant, not the law, as Arama; but rather, as some Jewish f594 interpreters understand it, the Messiah, the sun of righteousness, and light of the world; who is the author of all light, natural, spiritual, and eternal; and whose coming into the world is often signified by being sent into it. The Spirit of God also is the enlightener of men, both at first conversion and afterwards, and is sent down into their hearts as a comforter of them, by being the Spirit of adoption.

“43:3 In this prayer for God’s redemption, light and truth are viewed as guides (see 18:25-29; 27:1; 85:10-13; 89:14-18; see also 119:105; John 3:19; Eph 5:8; 1 Thes 5:5-7). • The Temple on the mountain in Jerusalem symbolized God’s holy presence among his people (Pss 15:1; 43:3; 99:5, 9; 132:7).”
