'Tails' in the Bible

Samson went and caught three hundred foxes, and took torches, and turned the foxes tail to tail and put one torch in the middle between two tails.

They have tails like scorpions, and stings; and in their tails is their power to hurt men for five months.

For the power of the horses is in their mouths and in their tails; for their tails are like serpents and have heads, and with them they do harm.
