Numbers 10:3

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

When they shall blow them, all the congregation shall gather themselves to you at the door of the tent of meeting.

And when they shall blow them, all the congregation shall gather themselves unto thee at the door of the tent of meeting.

and they have blown with them, and all the company have met together unto thee, unto the opening of the tent of meeting.

When both are sounded, the whole congregation is to assemble before you at the entrance to the Tent of Meeting.
