Leviticus 23:23-25: “ And the LORD spake unto Moses, saying,
 Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall ye have a sabbath, a memorial of blowing of trumpets, an holy convocation.
 Ye shall do no servile work therein: but ye shall offer an offering made by fire unto the LORD.”
The Memorial of Blowing of Trumpets is a HolyDayordained by YHWH. The Trumpet/Ram’s Horn was an instrument used for many reasons in Israelite culture. It was used to assemble the people, give warning, alert Israel of the Holy Days or a call to arms for battle.
Numbers 10:1-10: “ And the LORD spake unto Moses, saying,
 Make thee two trumpets of silver; of a whole piece shalt thou make them: that thou mayest use them for the calling of the assembly, and for the journeying of the camps.
 And when they shall blow with them, all the assembly shall assemble themselves to thee at the door of the tabernacle of the congregation.
 And if they blow but with one trumpet, then the princes, which are heads of the thousands of Israel, shall gather themselves unto thee.
 When ye blow an alarm, then the camps that lie on the east parts shall go forward.
 When ye blow an alarm the second time, then the camps that lie on the south side shall take their journey: they shall blow an alarm for their journeys.
 But when the congregation is to be gathered together, ye shall blow, but ye shall not sound an alarm.
 And the sons of Aaron, the priests, shall blow with the trumpets; and they shall be to you for an ordinance for ever throughout your generations.
 And if ye go to war in your land against the enemy that oppresseth you, then ye shall blow an alarm with the trumpets; and ye shall be remembered before the LORD your God, and ye shall be saved from your enemies.
 Also in the day of your gladness, and in your solemn days, and in the beginnings of your months, ye shall blow with the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; that they may be to you for a memorial before your God: I am the LORD your God.”
During this time it’s important to remember our calling as men and women of the Lord. Our mission must still be to gather the Lost Sheep of the House of Israel (Matthew 10:5- 6; John 21:15-17; Matthew 15:24). Men of the Most High must use their voices as the trumpets of the Lord to call the people back to the Lord through repentance. We must listen and adhere to the voice of Christ which is the trumpet we hear when we turn to the Lord and change our ways.
St. John 10:27-28: “ My sheep hear my voice, and I know them, and they follow me:  And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
Isaiah 58:1: “Cry aloud, spare not, lift up thy voice like a trumpet, and shew my people their transgression, and the house of Jacob their sins.”
Ezek 33:1-6: “ Again the word of the LORD came unto me, saying,
 Son of man, speak to the children of thy people, and say unto them, When I bring the sword upon a land, if the people of the land take a man of their coasts, and set him for their watchman:
 If when he seeth the sword come upon the land, he blow the trumpet, and warn the people;
 Then whosoever heareth the sound of the trumpet, and taketh not warning; if the sword come, and take him away, his blood shall be upon his own head.
 He heard the sound of the trumpet, and took not warning; his blood shall be upon him. But he that taketh warning shall deliver his soul.
 But if the watchman see the sword come, and blow not the trumpet, and the people be not warned; if the sword come, and take any person from among them, he is taken away in his iniquity; but his blood will I require at the watchman's hand.”
The Blowing of Trumpets is a Memorial to remember the sanctity of the Trumpet and its uses as well as to help us remember our mission as Israelites, the only children of YHWH.
