'Short' in the Bible

“When you sound short blasts, the camps pitched on the east are to set out.

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.

When calling the assembly together, you are to sound long blasts, not short ones.

“When you enter into battle in your land against an adversary who is attacking you, sound short blasts on the trumpets, and you will be remembered before the Lord your God and be delivered from your enemies.
