Matthew 21:2 speaks about a female donkey with the colt.
Now Zecharias 9:9 mentions a female donkey, a colt and a male donkey.
Translations in Hebrew for the female donkey is ATHOWN (Strong 0860) and it would probably come from the Hebrew word EYTHAN (Strong 0386) which means perpetual, constant, permanent, strong, mighty. The plural of this word is EYTHANIYM (Strong 0388), its litteral translation is « constant rains » and it is also the 7th jewish month which corresponds to October-November because of frequent rains during this season.
Translation in Hebrew for the colt is AYIR (Strong 05895) it comes, in the sense of raising (i.e. bearing a burden), from the Hebrew word ‘UWR (Strong 05782) which means to wake (stir, lift..)up, awake, wake, raise, arise. This word is rather identical, through the idea of opening the eyes,with ‘UWR (05783): to be bare, naked.
Translation in Hebrew for the male donkey is CHAMOWR which comes from CHAMAR (Strong 02560): to boil up; hence, to ferment (with scum); to glow (with redness); troubled, daub, foul.
Translation in Hebrew for the wild donkey is PERE’ (Strong 06501). In the sene of running wild, the onager, it comes from PARA’ (Strong 06500): to bear fruit, fruitful.

It seems like donkeys are used in essential events in the Bible.
And the most important one: Jesus entering Jerusalem on a colt that was TIED OUTSIDE, NEAR A DOOR, IN THE STREET, whom no one has ever ridden and Jesus commands the apostles to LOOSE him and the female donkey to BRING THEM UNTO HIM!
Genesis 49:11-12:
« 11 He will tether his donkey to a vine,
his colt to the choicest branch;
he will wash his garments in wine,
his robes in the blood of grapes.
12 His eyes will be darker than wine,
his teeth whiter than milk. »
