But when the congregation is to be gathered together, ye shall blow, but ye shall not sound an alarm.
When the congregation is to be assembled, you shall blow [the trumpets in short, sharp tones], but not the blast of an alarm.
But when the assembly is to be gathered together, ye shall blow, but ye shall not sound an alarm.
To gather the assembly, blow a long blast, not a series of short blasts.
But when the people are to be gathered together, the sound of the trumpets shall be simple, and the sounds shall not be separated.
