Synopsis of the Books of the Bible, by John Nelson Darby, [1857-62], at sacred-texts.com
The first, Psalm 3, gives the condition in general in contrast with Psalm 2, and the support and confidence of faith in it. The troublers of the godly man are multiplied, haughty, and triumphing over him as having no help in God; but Jehovah is his shield. He lies down in peace, and by faith sees his enemies smitten and their power destroyed. Salvation belongs to Jehovah, and His blessing is upon His people. Here again, remark, we find the latter days; and, though surrounded by his enemies, the godly man rests in peace and prophetically sees their destruction, and blessing on Israel. It expresses confidence in God in the midst of hostile numbers, and without resource. Christ has surely entered fully into this; but the place of the psalm is in the latter days, after proof of the non accomplishment of Psalm 2, at His first presenting Himself as Messiah to Israel.
