O ye children of Benjamin, gather yourselves to flee out of the midst of Jerusalem, and blow the trumpet in Tekoa, and set up a sign of fire in Bethhaccerem: for evil appeareth out of the north, and great destruction. O ye children of Benjamin, gather yourselves to flee - As the invading armies are fast approaching, the prophet calls on the inhabitants of Jerusalem to sound an alarm, and collect all the people to arm themselves and go against the invaders. They are called the children of Benjamin, because Jerusalem was in the tribe of Benjamin.
