gentle AND humble

Should these two words be so closely associated with each other let alone with donkeys? Which one of these pair looks well-named ‘Gentle’ and which one ‘Humble’?!  Surely ‘Jeremiah’ and ‘Hezekiah’ would be more fitting names!  Does society nowadays recognise and respect humility as an attribute – what is humility anyway?  The same question could be asked of ‘gentleness’.  Can you be gentle without being humble and vice versa?  Why are these two things important in a Christian and is it possible to be both?  So many questions need an answer to make sense of it all and these come in the person of Christ:

‘See, your king comes to you, gentle and riding on a donkey, and on a colt, the foal of a donkey’ – Matthew 21:5
