Abundance, supply: holy, kind – Amen (4,3,5)

Ross

I believe the answer is:

milk and honey

I'm a little stuck... Click here to teach me more about this clue!

'abundance' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'supply holy kind amen' is the wordplay.
'supply' is an anagram indicator (in a supple way).
'holy'+'kind'+'amen'='holykindamen'
'holykindamen' with letters rearranged gives 'MILK AND HONEY'.

Can you help me to learn more?
