For thou wilt light my candle,.... Or lamp (d): in Sa2 22:29, it is, "Thou art my lamp, O Lord"; which may either design outward prosperity, and the flourishing condition of David's kingdom; or internal spiritual light, and an increase of it, by giving fresh supplies of the oil of grace, to cause the lamp to burn more clearly; or rather the prosperous estate of Christ's kingdom; and may be the same with the lamp ordained for the Messiah, Psa 132:17; the Lord my God will enlighten my darkness; or "cause light to shine in my darkness" (e); that is, bring me out of darkness into light; either out of adversity to prosperity, or from walking in darkness to the enjoyment of the light of his countenance; and is true of Christ, not only of the prosperity of his kingdom and interest, but of him personally; who though, when on the cross, was in darkness of soul, being forsaken by his God; yet, when raised from the dead, he was received up to heaven, and set down at the right hand of God, and was made full of joy with his countenance, Act 2:28.
