³ When they both are blown, all the congregation shall assemble before you at the door of the Tent of Meeting.

⁴ And if one blast on a single trumpet is blown, then the princes or leaders, heads of the tribes of Israel, shall gather themselves to you.

⁵ When you blow an alarm, the camps on the east side [of the tabernacle] shall set out.
