Numbers 10:2-4

New American Standard Bible

² “Make yourself two trumpets of silver, you shall make them of hammered work; and you shall use them for ^(A)summoning the congregation and breaking camp. ³ Now ^(B)when both are blown, all the congregation shall meet you at the entrance of the tent of meeting. ⁴ But if only one is blown, then the ^(C)leaders, the heads of the ^[a]divisions of Israel, shall meet you.
