³⁵ Then came some priests who played trumpets, including Zechariah son of Jonathan, son of Shemaiah, son of Mattaniah, son of Micaiah, son of Zaccur, a descendant of Asaph.

¹⁷ Also Mattaniah son of Mica, son of Zabdi, a descendant of Asaph, who led in thanksgiving and prayer. Also Bakbukiah, who was Mattaniah’s assistant, and Abda son of Shammua, son of Galal, son of Jeduthun.

¹² So you see, God is with us. He is our leader. His priests blow their trumpets and lead us into battle against you. O people of Israel, do not fight against the Lord, the God of your ancestors, for you will not succeed!”

¹² And the Levites who were musicians—Asaph, Heman, Jeduthun, and all their sons and brothers—were dressed in fine linen robes and stood at the east side of the altar playing cymbals, lyres, and harps. They were joined by 120 priests who were playing trumpets.

¹⁰ Hosah, of the Merari clan, appointed Shimri as the leader among his sons, though he was not the oldest. ¹¹ His other sons included Hilkiah (the second), Tebaliah (the third), and Zechariah (the fourth). Hosah’s sons and relatives, who served as gatekeepers, numbered thirteen in all.

² From the sons of Asaph, there were Zaccur, Joseph, Nethaniah, and Asarelah. They worked under the direction of their father, Asaph, who proclaimed God’s messages by the king’s orders.

³⁹ Heman’s first assistant was Asaph from the clan of Gershon.^[a] Asaph’s genealogy was traced back through Berekiah, Shimea, ⁴⁰ Michael, Baaseiah, Malkijah, ⁴¹ Ethni, Zerah, Adaiah, ⁴² Ethan, Zimmah, Shimei, ⁴³ Jahath, Gershon, and Levi.

⁴ Seven priests will walk ahead of the Ark, each carrying a ram’s horn. On the seventh day you are to march around the town seven times, with the priests blowing the horns.

² “Make two trumpets of hammered silver for calling the community to assemble and for signaling the breaking of camp. ³ When both trumpets are blown, everyone must gather before you at the entrance of the Tabernacle.^{[a] 4} But if only one trumpet is blown, then only the leaders—the heads of the clans of Israel—must present themselves to you.

⁵ “When you sound the signal to move on, the tribes camped on the east side of the Tabernacle must break camp and move forward. ⁶ When you sound the signal a second time, the tribes camped on the south will follow. You must sound short blasts as the signal for moving on. ⁷ But when you call the people to an assembly, blow the trumpets with a different signal. ⁸ Only the priests, Aaron’s descendants, are allowed to blow the trumpets. This is a permanent law for you, to be observed from generation to generation.

⁹ “When you arrive in your own land and go to war against your enemies who attack you, sound the alarm with the trumpets. Then the Lord your God will remember you and rescue you from your enemies. ¹⁰ Blow the trumpets in times of gladness, too, sounding them at your annual festivals and at the beginning of each month. And blow the trumpets over your burnt offerings and peace offerings. The trumpets will remind your God of his covenant with you. I am the Lord your God.”
