Numbers 10:2 WBT

¹  And the LORD spoke to Moses, saying,

²  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.

³  And when they shall blow with them, all the assembly shall assemble themselves to thee at the door of the tabernacle of the congregation.

⁴  And if they blow [but] with one [trumpet], then the princes, [who are] heads of the thousands of Israel, shall assemble themselves to thee.
