A dove about to be caught in a tree was scared away because an ant, seeing the problem, stung the bird catcher who then yelled.
Return favors given to you.
An ant went to the bank of a river to quench its thirst, and being carried away by the rush of the stream, was on the point of drowning. A Dove sitting on a tree overhanging the water plucked a leaf and let it fall into the stream close to her. The Ant climbed onto it and floated in safety to the bank. Shortly afterwards a birdcatcher came and stood under the tree, and laid his lime-twigs [birdlime] for the Dove, which sat in the branches. The Ant, perceiving his design, stung him in the foot. In pain the birdcatcher threw down the twigs, and the noise made the Dove take wing.
[Note: The JBR and Aesop for Children versions slightly differ in detail but are still the same.]
Aesop For Children
A Dove saw an Ant fall into a brook. The Ant struggled in vain to reach the bank, and in pity, the Dove dropped a blade of straw close beside it. Clinging to the straw like a shipwrecked sailor to a broken spar, the Ant floated safely to shore.
Soon after, the Ant saw a man getting ready to kill the Dove with a stone. But just as he cast the stone, the Ant stung him in the heel, so that the pain made him miss his aim, and the startled Dove flew to safety in a distant wood.
A kindness is never wasted.
An Ant going to a river to drink, fell in, and was carried along in the stream. A Dove pitied her condition, and threw into the river a small bough, by means of which the Ant gained the shore. The Ant afterwards, seeing a man with a fowling-piece aiming at the Dove, stung him in the foot sharply, and made him miss his aim, and so saved the Dove’s life.
Formica et Columba
Formica, sitiens, cum ad fontem descendisset ut biberet, in aquam cecidit nec multum abfuit quin misera periret. Columba quaedam, in arbore sedens, misericordia tacta, ramulum in aquam iniecit. Hunc assecuta est formica, eique innatans, mortem effugit. Paulo post adfuit auceps, qui columbae insidiabatur. Formica, ut piae columbae opem ferret, ad aucupem arrepsit et tam vehementer eum momordit ut harundines prae dolore abiiceret. Columba, strepitu harundinum territa, avolavit ac periculum incolumis evasit.
Iuva et iuvabere; raro beneficium perit.
