The Hebrew words having these meanings are each of two letters, the initial one being the same in both, and both words having the same sound. Confusion might easily therefore arise, and as a matter of fact there are numerous cases in which the text has the one and the margin the other of these two words. Here, if we adhere to the text, we read the negative, and then the force of the clause is to declare emphatically that the "days" were written in God's book, and in a real sense "fashioned," when as yet they had not been recorded in earth's calendars. If, on the other hand, the marginal reading is preferred, a striking meaning is obtained: "And for it [_i.e._, for the birth of the shapeless mass] there was one among them [predestined in God's book]." In vv. 17, 18, the poet gathers together and crowns all his previous contemplations by the consideration that this God, knowing him altogether, ever near him, and Former of his being, has great "thoughts" or purposes affecting him individually. That assurance makes omniscience and omnipresence joys, and not terrors. The root meaning of the word rendered "precious" is _weighty_. The singer would weigh God's thoughts towards him, and finds that they weigh down his scales. He would number them, and finds that they pass his enumeration. It is the same truth of the transcendent greatness and graciousness of God's purposes as is conveyed in Isaiah's "As the heavens are higher than the earth, so are . . . My thoughts than your thoughts." "I awake, and am still with Thee,"--this is an artless expression of the psalmist's blessedness in realising God's continual nearness. He awakes from sleep, and is conscious of glad wonder to find that, like a tender mother by her slumbering child, God has been watching over him, and that all the blessed communion of past days abides as before. The fiery hatred of evil and evil men which burns in the last strophe offends many and startles more. But while the vehement prayer that "Thou wouldest slay the wicked" is not in a Christian tone, the recoil from those who could raise themselves against such a God is the necessary result of the psalmist's delight in Him. Attraction and repulsion are equal and contrary. The measure of our cleaving to that which is good, and to Him who is good, settles the measure of our abhorrence of that which is evil. The abrupt passing from petition in ver. 19_a_ to command in _b_ has been smoothed away by a slight alteration which reads, "And that men of blood would depart from me"; but the variation in tense is more forcible, and corresponds with the speaker's strong emotion. He cannot bear companionship with rebels against God. His indignation has no taint of personal feeling, but is pure zeal for God's honour.
