'Tails' in the Bible

Samson went and captured three hundred jackals and got some torches. He tied the jackals in pairs by their tails and then tied a torch to each pair.

They have tails and stingers like scorpions, and their ability to injure people for five months is in their tails.

For the power of the horses resides in their mouths and in their tails, because their tails are like snakes, having heads that inflict injuries.
