The words of our text gain especial force and vividness by thus localising the psalm. Not only 'the clefts of the rock' but the presence of God's Angel is his defence; and round him is flung, not only the strength of the hills, but the garrison and guard of heaven. It is generally supposed that the 'Angel of the Lord' here is to be taken collectively, and that the meaning is--the 'bright-harnessed' hosts of these divine messengers are as an army of protectors round them who fear God. But I see no reason for departing from the simpler and certainly grander meaning which results from taking the word in its proper force of a singular. True, Scripture does speak of the legions of ministering spirits, who in their chariots of fire were once seen by suddenly opened eyes 'round about' a prophet in peril, and are ever ministering to the heirs of salvation. But Scripture also speaks of One, who is in an eminent sense 'the Angel of the Lord'; in whom, as in none other, God sets His 'Name'; whose form, dimly seen, towers above even the ranks of the angels that 'excel in strength'; whose offices and attributes blend in mysterious fashion with those of God Himself. There may be some little incongruity in thinking of the single Person as 'encamping round about' us; but that does not seem a sufficient reason for obliterating the reference to that remarkable Old Testament doctrine, the retention of which seems to me to add immensely to the power of the words. Remember some of the places in which the 'Angel of the Lord' appears, in order to appreciate more fully the grandeur of this promised protection. At that supreme moment when Abraham 'took the knife to slay his son,' the voice that 'called to him out of heaven' was 'the voice of the Angel of the Lord.' He assumes the power of reversing a divine command. He says, 'Thou hast not withheld thy son, thine only son, from _Me_,' and then pronounces a blessing, in the utterance of which one cannot distinguish His voice from the voice of Jehovah. In like manner it is the Angel of the Lord that speaks to Jacob, and says, 'I am the God of Bethel.' The dying patriarch invokes in the same breath 'the God which fed me all my life long,' 'the Angel which redeemed me from all evil,' to bless the boys that stand before him, with their wondering eyes gazing in awe on his blind face. It was that Angel's glory that appeared to the outcast, flaming in the bush that burned unconsumed. It was He who stood before the warrior leader of Israel, sword in hand, and proclaimed Himself to be the Captain of the Lord's host, the Leader of the armies of heaven, and the true Leader of the armies of Israel; and His commands to Joshua, His lieutenant, are the commands of 'the Lord.' And, to pass over other instances, Isaiah correctly sums up the spirit of the whole earlier history in words which go far to lift the conception of this Angel of the Lord out of the region of created
