Numbers 10:4

But if only one is sounded, then the leaders, the heads of the clans of Israel, are to gather before you.

And if they blow but with one trumpet, then the princes, which are heads of the thousands of Israel, shall gather themselves unto thee.

If they blow just one, then the princes, the heads of the thousands of Israel, shall gather themselves to you.

And if they blow but one, then the princes, the heads of the thousands of Israel, shall gather themselves unto thee.
