In the second Isaiah there are numerous references to 'the arm of the Lord.' It is a natural symbol of the active energy of Jehovah, and is analogous to the other symbol of 'the Face of Jehovah,' which is also found in this book, in so far as it emphasises the notion of power in manifestation, though 'the Face' has a wider range and may be explained as equivalent to that part of the divine Nature which is turned to men. The latter symbol will then be substantially parallel with 'the Name.' But there are traces of a tendency to conceive of 'the arm of the Lord' as personified, for instance, where we read (ch. lxiii. 12) that Jehovah 'caused His glorious arm to go at the right hand of Moses.' Moses was not the true leader, but was himself led and sustained by the divine Power, dimly conceived as a person, ever by his side to sustain and direct. There seems to be a similar imperfect consciousness of personification in the words of the text, especially when taken in their close connection with the immediately following prophecy of the suffering servant. It would be doing violence to the gradual development of Revelation, like tearing asunder the just-opening petals of a rose, to read into this question of the sad prophet full-blown Christian truth, but it would be missing a clear anticipation of that truth to fail to recognise the forecasting of it that _is_ here. I. We have here a prophetic forecast that the arm of the Lord is a person. The strict monotheism of the Old Testament does not preclude some very remarkable phenomena in its modes of conception and speech as to the divine Nature. We hear of the 'angel of His face,' and again of 'the angel in whom is His Name.' We hear of 'the angel' to whom divine worship is addressed and who speaks, as we may say, in a divine dialect and does divine acts. We meet, too, with the personification of Wisdom in the Book of Proverbs, to which are ascribed characteristics and are attributed acts scarcely distinguishable from divine, and eminently associated in the creative work. Our text points in the same direction as these representations. They all tend in the direction of preparing for the full Christian truth of the personal 'Power of God.' What was shown by glimpses 'at sundry times and in divers manners,' with many gaps in the showing and much left all unshown, is perfectly revealed in the Son. The New Testament, by its teaching as to 'the Eternal Word,' endorses, clears, and expands all these earlier dimmer adumbrations. That Word is the agent of the divine energy, and the conception of power as being exercised by the Word is even loftier than that of it as put forth by 'the arm,' by as much as intelligent and intelligible utterance is more spiritual and higher than force of muscle. The apostolic designation of Jesus as 'the power of God and the wisdom of God' blends the two ideas of these two symbols. The conception of Jesus Christ as the arm of the Lord, when united with that of the Eternal
