And he shall send his angels - “Angels” signify, literally, “messengers,” Luke 7:24; Luke 9:52. The word is often applied to inanimate objects, or to anything that God employs to rescue his people from danger Psalms 104:4; but it most commonly refers to the race of intelligent beings more exalted than man, who are employed often in the work of man’s rescue from ruin, and aiding his salvation, Hebrews 1:14. In either of these senses it might here refer to deliverance granted to his people in the calamities of Jerusalem. It is said that there is reason to believe that not one Christian perished in the destruction of that city, God having in various ways secured their escape, so that they fled to Pella, where they lived when the city was destroyed. But the language seems to refer rather to the end of the world, and, no doubt, its principal application was intended to be to the gathering of his elect at the day of judgment:
With a great sound of a trumpet - The Jewish assemblies used to be called together by the sound of a trumpet, as ours are by bells, Leviticus 25:9; Numbers 10:2; Judges 3:27. Hence, when they spoke of convening an assembly, they spoke also of doing it by sounding a trumpet. Our Saviour, speaking to Jews, used language to which they were accustomed, and described the assembling of the people at the last day in language which they were accustomed to use in calling assemblies together. It is not certain, however, that he meant that this would be literally so, but it may be designed only to denote the certainty that the “world would be assembled together.” Similar language is often used when speaking of the judgment, 1 Thessalonians 4:16; 1 Corinthians 15:52. A trump, or trumpet, was a wind instrument, made at first from the horns of oxen, and afterward of rams’ horns, cut off at the smaller extremity. In some instances it was made of brass, in the form of a horn. The common trumpet was straight, made of brass or silver, a cubit in length, the larger extremity shaped so as to resemble a small bell. In times of peace, in assembling the people, this was sounded softly. In times of calamity, or war, or any great commotion, it was sounded loud. Perhaps this was referred to when our Saviour said, with a great sound of a trumpet.
They shall gather together his elect - Elect. See the notes at Matthew 24:22. The word means Christians - the chosen of God. If this refers to the destruction of Jerusalem, it means, “God shall send forth his messengers - whatever he may choose to employ for that purpose: signs, wonders, human messengers, or the angels themselves - and gather Christians into a place of safety, so that they shall not be destroyed with the Jews.” If it refers to the last judgment, as it doubtless in a primary or secondary sense does, then it means that he will send his angels to gather his chosen, his elect, together from all places, Matthew 13:39, Matthew 13:41-43. This shall be done before the living shall be changed, 1 Corinthians 15:51-52; 1 Thessalonians 4:16-17.
From the four winds - That is, from the four quarters of the globe - east, west, north, and south. The Jews expressed those quarters by the winds blowing from them See Ezekiel 37:9. See also Isaiah 43:5-6. “From one end of heaven, etc.” Mark says Mark 13:27, from the uttermost part of the earth to the uttermost part of heaven. The expression denotes that they shall be gathered from all parts of the earth where they are scattered. The word “heaven” is used here to denote the “visible” heavens or the sky, meaning that through “the whole world” he would gather them. See Psalms 19:1-7; Deuteronomy 4:32.
