'Sounded' in the Bible

When both are sounded in long blasts, the entire community is to gather before you at the entrance to the tent of meeting.

However, if one is sounded, only the leaders, the heads of Israel’s clans, are to gather before you.

When you sound short blasts a second time, the camps pitched on the south are to set out. Short blasts are to be sounded for them to set out.
