(4) The voice of one crying in the wilderness.--See Note on Matthew 3:3.

(4) From David to Abraham there is a general agreement, the only variation being that, in some MSS., the names of Arni and Admei in St. Luke (Luke 3:33) replace the Aram of St. Matthew.

(4) The comparative slight variation here is such as may easily have arisen in the process of transcription from an Aramaic document into Greek. The received reading, "Aram," was probably a correction in order to bring the genealogy into agreement with St. Matthew's.

Verse 4. - As it is written in the book of the words of Esaias the prophet, saying, voice of one crying in the wilderness. The prophet quoted (Isaiah 40:3) had been writing in his solitude, or more probably in some great popular assembly preaching to the people. There was doubtless at that time much national trouble threatening Israel; the future of the chosen race looked very dark and gloomy, within and without. We can hear the man of God speaking with intense earnestness, and looking on to brighter times. "Comfort ye, comfort ye my people, saith your God. Speak ye comfortably to Jerusalem, and cry unto her, that her warfare is accomplished, that her iniquity is pardoned," etc.; and then a sudden burst when the prophet, bending forward and straining his ears to hear some sound none other caught but he, goes on in his rapt utterance - I hear a voice, "The voice of him that crieth in the wilderness, Prepare ye the way of the Lord." Prepare ye the way of the Lord, make his paths straight. The image is a simple one, and in the East one well knows, where the roads are comparatively few, and where they do exist are often in a bad state, when a sovereign is about to visit any part of his dominions, or still more if the march of an army has to be arranged for, the roads require considerable preparation. Josephus ('Bell. Jud.,' 3:06) describes the advance of the Emperor Vespasian's army, and specially mentions how the pioneers and the vanguard had to make the road even and straight, and, if it were anywhere rough hard to be passed over, to plane it. There was a Jewish legend that this special pioneering work in the desert was done by the pillar of cloud and fire, which brought low the mountains and filled the valleys before the Israelitic march. John's special work was to prepare the way for the advent of a Messiah very different to the one the people looked for - to prepare his way by a spiritual reformation in the heart, the mind, and the character.

3:1-14 The scope and design of John's ministry were, to bring the people from their sins, and to their Saviour. He came preaching, not a sect, or party, but a profession; the sign or ceremony was washing with water. By the words here used John preached the necessity of repentance, in order to the remission of sins, and that the baptism of water was an outward sign of that inward cleansing and renewal of heart, which attend, or are the effects of true repentance, as well as a profession of it. Here is the fulfilling of the Scriptures, Isa 40:3, in the ministry of John. When way is made for the gospel into the heart, by taking down high thoughts, and bringing them into obedience to Christ, by levelling the soul, and removing all that hinders us in the way of Christ and his grace, then preparation is made to welcome the salvation of God. Here are general warnings and exhortations which John gave. The guilty, corrupted race of mankind is become a generation of vipers; hateful to God, and hating one another. There is no way of fleeing from the wrath to come, but by repentance; and by the change of our way the change of our mind must be shown. If we are not really holy, both in heart and life, our profession of religion and relation to God and his church, will stand us in no stead at all; the sorer will our destruction be, if we do not bring forth fruits meet for repentance. John the Baptist gave instructions to several sorts of persons. Those that profess and promise repentance, must show it by reformation, according to their places and conditions. The gospel requires mercy, not sacrifice; and its design is, to engage us to do all the good we can, and to be just to all men. And the same principle which leads men to forego unjust gain, leads to restore that which is gained by wrong. John tells the soldiers their duty. Men should be cautioned against the temptations of their employments. These answers declared the present duty of the inquirers, and at once formed a test of their sincerity. As none can or will accept Christ's salvation without true repentance, so the evidence and effects of this repentance are here marked out.As it is written in the book of the words of Esaias the prophet,.... Isaiah 40:3
