(14) The light of the world.--In its highest or truest sense the word belongs to Christ, and to Him only (John 1:9; John 8:12). The comparison to the "candle" or "lamp" in Matthew 5:15 shows, indeed, that even here the disciples are spoken of as shining in the world with a derived brightness flowing to them from the Fount of light.

A city that is set on an hill.--Assuming the Sermon on the Mount to have been preached from one of the hills of Galilee near the "horns of Hattin," our Lord may have looked or pointed at Safed, 2,650 feet above the sea, commanding one of the grandest panoramic views in Palestine. It is now one of the four holy cities of the Jews, and probably existed as a fortress in our Lord's time (Thomson's The Land and the Book, p. 273). The imagery might, however, come from the prophetic visions of the Zion of the future, idealising the position of the actual Zion (Isaiah 2:2; Micah 4:1). No image could so vividly set forth the calling of the Church of Christ as a visible society. For good or for evil, it could not fail to be prominent in the world's history, a city of refuge for the weary, or open to the attacks of the invader.

Verse 14. - Matthew only. Ye are the light of the world. After speaking of the moral tone that the disciples were to give to the world, in contrast to sin in its corrupting power, Christ refers to them as enlightening, in contrast to sin as darkness and ignorance. Our Lord further naturally exchanges the term "the earth" (which from its strong materialism had suited the figure of the salt) for "the world" - a phrase which must, indeed, as regards the disciples, be limited to this earth, but as regards the light, need not be limited to less than the solar system. In other words, the simple reason why he exchanges "earth" for "world" is that they are respectively the best suited to the figure employed. Notice that Christ never applies the former figure, of salt, to himself; but the latter, of light, once or twice, especially John 8:12, where, since he is speaking of himself, and not of others, he adds the thought of life being connected with light, a city, etc.; literally, a city cannot be hid when set on a mountain. It seems at first slightly awkward to introduce the figure of a city between those of the sun and the lamp, both these having to do with light. The reason is that the city is not considered as such, but only as an object which can be teen, and which cannot (οὐ δύναται, emphatic) from its physical conditions avoid being seen. There is a true gradation in the thought of influence. The sun must be seen by all; the city, by the whole neighbourhood; the lamp, by the family. Our Lord comes from the general to the particular; from what is almost theory, at best a matter of hope and faith, to hard fact and practice. The influence you are to have - if it is to be for the whole world, as indeed it is, must be felt in the neighbourhood in which you live, and a fortiori in the immediate circle of your own home. Conjectures have been made whether any one city can reasonably be mentioned as being in sight, and so having suggested this image to our Lord. If the exact spot where he was then sitting were itself certain, such conjectures might be worth considering. But, in fact, so many "cities" in Palestine were set on hills that the inquiry seems vain. Safed, some twelve miles north-west of Capernaum, the view from which extends to Tiberias (Neubaur, 'Geogr.,' p. 228), has been accepted by many, but evidence is lacking for it having been a city at that time. Tabor, at the south-west of the lake, has also been thought of, and at all events seems to have been then a fortified town. The view from it is even more extensive than from Safed (vide especially Socin's Baedeker, p. 365).

5:13-16 Ye are the salt of the earth. Mankind, lying in ignorance and wickedness, were as a vast heap, ready to putrify; but Christ sent forth his disciples, by their lives and doctrines to season it with knowledge and grace. If they are not such as they should be, they are as salt that has lost its savour. If a man can take up the profession of Christ, and yet remain graceless, no other doctrine, no other means, can make him profitable. Our light must shine, by doing such good works as men may see. What is between God and our souls, must be kept to ourselves; but that which is of itself open to the sight of men, we must study to make suitable to our profession, and praiseworthy. We must aim at the glory of God.Ye are the light of the world,.... What the luminaries, the sun and moon, are in the heavens, with respect to corporal light, that the apostles were in the world with regard to spiritual light; carrying and spreading the light of the Gospel not only in Judea, but all over the world, which was in great darkness of ignorance and error; and through a divine blessing attending their ministry, many were turned from the darkness of Judaism and Gentilism, of sin and infidelity, to the marvellous light of divine grace. The Jews were wont to say, that of the Israelites in general, and particularly of their sanhedrim, and of their learned doctors, what Christ more truly applies here to his apostles; they observe (l), that

"on the fourth day it was said, "let there be light": which was done with respect to the Israelites, because they are they , "which give light to the world", as it is written, Daniel 12:3'

And in another place (m), say they,

"how beautiful are the great ones of the congregation, and the wise men, who sit in the sanhedrim! for they are they , "that enlighten the world", the people of the house of Israel.''

So. R. Meir, R. Akiba his disciple, and R. Judah the prince, are each of them called (n) , "the light of the world"; as R. Jochanan ben Zaccai is by his disciples, , "the lamp of the world" (o): and it was usual for the head of a school, or of an university to be styled (p) , "the light of the world"; but this title much better agrees and suits with the persons Christ gives it to, who, no question, had a view to those exalted characters the Jews gave to their celebrated Rabbins. A city that

is set on an hill cannot be hid; alluding either to Nazareth, where he was educated, and had lately preached, which was built on an hill, from the brow of which the inhabitants sought to have cast him headlong, Luke 4:29 or to Capernaum, which, on account of its height, is said to be

exalted unto heaven, Matthew 11:23 or to the city of Jerusalem, which was situated on a very considerable eminence. The land of Israel, the Jews say (q), was higher than all other lands; and the temple at Jerusalem was higher than any other part of the land of Israel. And as a city cannot be hid which is built on a high place, so neither could, nor ought the doctrines which the apostles were commissioned to preach, be hid, or concealed from men: they were not to shun to declare the whole counsel of God, nor study to avoid the reproaches and persecutions of men; for they were to be "made a spectacle"; to be set as in a public theatre, to be seen by "the world, angels, and men".
