Feast of Trumpets (7th New Moon)

Feast of Trumpets

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.
(Leviticus 23:23-25)

And in the seventh month, on the first day of the month, ye shall have an holy convocation; ye shall do no servile work: it is a day of blowing the trumpets unto you.
(Numbers 29:1)

Sing aloud unto God our strength: make a joyful noise unto the God of Jacob. Take a psalm, and bring hither the timbrel, the pleasant harp with the psaltery. Blow up the trumpet in the new moon, in the time appointed, on our solemn feast day. For this was a statute for Israel, and a law of the God of Jacob.
(Psalms 81:1-4)

The LORD hath made known his salvation: his righteousness hath he openly shewed in the sight of the heathen. He hath remembered his mercy and his truth toward the house of Israel: all the ends of the earth have seen the salvation of our God. Make a joyful noise unto the LORD, all the earth: make a loud noise, and rejoice, and sing praise. Sing unto the LORD with the harp; with the harp, and the voice of a psalm. With trumpets and sound of cornet make a joyful noise before the LORD, the King. (Psalms 98:1-6)

This Feast of Trumpets is a new moon Conjunction, set apart from the rest of the month.
