PSALM 27[A Psalm] of David. The Septuagint interpreters add to this title, "before he was anointed". David was anointed three times, first when a youth in his father's house; but this psalm could not be written before that time, because he had not had then any experience of war, nor could be in any immediate apprehension of it, as here suggested; he was anointed a second time, after the death of Saul at Hebron, by the men of Judah; before that time indeed he had been harassed by Saul, and distressed by the Amalekites, and was driven from the public worship of God, to which he has a respect, Ps 27:4; and he was a third time anointed, by the elders of Israel, king over all Israel; and between the death of Saul and this unction there was a war between the house of David and the house of Saul; but what is referred to is not certain, nor is it of moment, since these words are neither in the Hebrew text, nor in the Chaldee paraphrase.
Theodoret is of opinion this psalm was written by David when he fled from Saul, and came to Ahimelech the priest.Ver. 1. The Lord [is] my light and my salvation; whom shall I fear?.... The Targum in the king of Spain's Bible explains it, "the Word of the Lord is my light"; and so Ainsworth cites it; that is, Christ the eternal Word, in whom "was life, and that life was the light of men", Joh 1:4; and the psalmist is not to be understood of the light of nature and reason, with which the Logos, or Word, enlightens every man that comes into the world; nor merely in a temporal sense, of giving him the light of prosperity, and delivering him from the darkness of adversity; but of the light of grace communicated to him by him who is the sun of righteousness, and the light of the world; and by whom such who are darkness itself, while in an unregenerate state, are made light, and see light; all the light which is given to men at first conversion is from Christ; and all the after communications and increase of it are from him; as well as all that spiritual joy, peace, and comfort they partake of, which light sometimes signifies, Ps 97:11; and which the psalmist now had an experience of; enjoying the light of God's countenance, and having discoveries of his love, which made him fearless of danger and enemies: and such who are made light in the Lord have no reason to be afraid of the prince of darkness; nor of the rulers of the darkness of this world; nor of all the darkness, distress, and persecutions they are the authors of; nor of the blackness of darkness reserved for ungodly men; for their light is an everlasting one, and they are made meet to be partakers of the inheritance with the saints in light: and the more light they have, the less fear; and what made the psalmist still more fearless was, that Christ was his "salvation"; by the light which the Lord was to him, he saw his need of salvation, he knew that his own righteousness would not save him; he was made acquainted with the design and appointment of the Lord, that Christ should be salvation to the ends of the earth; he had knowledge of the covenant of grace, and faith in it, which was all his salvation, 2Sa 23:5.
Salvation was revealed to the Old Testament saints, in the promises, sacrifices, types, and figures of that dispensation; and they looked through them to him for it, and were saved by him, as New Testament believers are; and they had faith of interest in Christ, and knew him to be their Saviour and Redeemer, as did Job, and here the psalmist David: and such who know Christ to be their salvation need not be afraid of any person or thing; not of sin, for though they fear, and should fear to commit it, they need not fear the damning power of it, for they are saved from it; nor of Satan, out of whose hands they are ransomed; nor of the world, which is overcome by Christ; nor of the last enemy, death, which is abolished by him; nor of hell, and wrath to come, for he has delivered them from it;the Lord [is] the strength of my life; of whom shall I be afraid?
